a84724178b selftests: net: tcp_mmap: fix SO_RCVLOWAT setting
Since chunk_size is no longer an integer, we can not
use it directly as an argument of setsockopt().

This patch should fix tcp_mmap for Big Endian kernels.

bf5525f3a8 selftests: net: tcp_mmap: clear whole tcp_zerocopy_receive struct
We added fields in tcp_zerocopy_receive structure,
so make sure to clear all fields to not pass garbage to the kernel.

We were lucky because recent additions added 'out' parameters,
still we need to clean our reference implementation, before folks
copy/paste it.

3aeaaa59fd selftests:mptcp: fix failure due to whitespace damage
'pm_nl_ctl' was adding a trailing whitespace after having printed the
IP. But at the end, the IP element is currently always the last one.

The bash script launching 'pm_nl_ctl' had trailing whitespaces in the
expected result on purpose. But these whitespaces have been removed when
the patch has been applied upstream. To avoid trailing whitespaces in
the bash code, 'pm_nl_ctl' and expected results have now been adapted.

The MPTCP PM selftest can now pass again.

83a9b6f639 selftests/net: add definition for SOL_DCCP to fix compilation errors for old libc
Many systems build/test up-to-date kernels with older libcs, and
an older glibc (2.17) lacks the definition of SOL_DCCP in
/usr/include/bits/socket.h (it was added in the 4.6 timeframe).

Adding the definition to the test program avoids a compilation
failure that gets in the way of building tools/testing/selftests/net.
The test itself will work once the definition is added; either
skipping due to DCCP not being configured in the kernel under test
or passing, so there are no other more up-to-date glibc dependencies
here it seems beyond that missing definition.

This commit adds a test to check if we can fully utilize 4-tuples for
connect() when all ephemeral ports are exhausted.

The test program changes the local port range to use only one port and binds
two sockets with or without SO_REUSEADDR and SO_REUSEPORT, and with the same
EUID or with different EUIDs, then do listen().

We should be able to bind only one socket having both SO_REUSEADDR and
SO_REUSEPORT per EUID, which restriction is to prevent unintentional
listen().

Currently the SW-datapath ETS selftests use "ip link" stats to obtain the
number of packets that went through a given band. mlxsw then uses ethtool
per-priority counters.

Instead, change both to use qdiscs. In SW datapath this is the obvious
choice, and now that mlxsw offloads FIFO, this should work on the offloaded
datapath as well. This has the effect of verifying that the FIFO offload
works.

b9167c8078 selftests: Install settings files to fix TIMEOUT failures
Commit 852c8cbf34 ("selftests/kselftest/runner.sh: Add 45 second
timeout per test") added a 45 second timeout for tests, and also added
a way for tests to customise the timeout via a settings file.

For example the ftrace tests take multiple minutes to run, so they
were given longer in commit b43e78f65b ("tracing/selftests: Turn off
timeout setting").

This works when the tests are run from the source tree. However if the
tests are installed with "make -C tools/testing/selftests install",
the settings files are not copied into the install directory. When the
tests are then run from the install directory the longer timeouts are
not applied and the tests timeout incorrectly.

So add the settings files to TEST_FILES of the appropriate Makefiles
to cause the settings files to be installed using the existing install
logic.

e404b8c7cf ipv6: Fix route replacement with dev-only route
After commit 2759647247 ("ipv6: fix ECMP route replacement") it is no
longer possible to replace an ECMP-able route by a non ECMP-able route.
For example,
	ip route add 2001:db8::1/128 via fe80::1 dev dummy0
	ip route replace 2001:db8::1/128 dev dummy0
does not work as expected.

Tweak the replacement logic so that point 3 in the log of the above commit
becomes:
3. If the new route is not ECMP-able, and no matching non-ECMP-able route
exists, replace matching ECMP-able route (if any) or add the new route.

We can now summarize the entire replace semantics to:
When doing a replace, prefer replacing a matching route of the same
"ECMP-able-ness" as the replace argument. If there is no such candidate,
fallback to the first route found.

e8023b030c selftests: forwarding: use proto icmp for {gretap, ip6gretap}_mac testing
For tc ip_proto filter, when we extract the flow via __skb_flow_dissect()
without flag FLOW_DISSECTOR_F_STOP_AT_ENCAP, we will continue extract to
the inner proto.

So for GRE + ICMP messages, we should not track GRE proto, but inner ICMP
proto.

For test mirror_gre.sh, it may make user confused if we capture ICMP
message on $h3(since the flow is GRE message). So I move the capture
dev to h3-gt{4,6}, and only capture ICMP message.

3e8393630e selftests: use LDLIBS for libraries instead of LDFLAGS
While building selftests, the following errors were observed:
> tools/testing/selftests/timens'

> timens.c:(.text+0x65a): undefined reference to `timer_create'
> collect2: error: ld returned 1 exit status

Quoting commit 870f193d48 ("selftests: net: use LDLIBS instead of
LDFLAGS"):

The default Makefile rule looks like:

$(CC) $(CFLAGS) $(LDFLAGS) $@ $^ $(LDLIBS)

When linking is done by gcc itself, no issue, but when it needs to be passed
to proper ld, only LDLIBS follows and then ld cannot know what libs to link
with.

More detail:
https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html

LDFLAGS
Extra flags to give to compilers when they are supposed to invoke the linker,
‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable
instead.

LDLIBS
Library flags or names given to compilers when they are supposed to invoke the
linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to
LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS
variable.

While at here, correct other selftests, not only timens ones.

Turns out that when we accept a new subflow, the newly created
inet_sk(tcp_sk)->pinet6 points at the ipv6_pinfo structure of the
listener socket.

This wasn't caught by the selftest because it closes the accepted fd
before the listening one.

adding a close(listenfd) after accept returns is enough:

af8c8a450b selftests: net: Add FIN_ACK processing order related latency spike test
This commit adds a test for FIN_ACK process races related reconnection
latency spike issues.  The issue has described and solved by the
previous commit ("tcp: Reduce SYN resend delay if a suspicous ACK is
received").

The test program is configured with a server and a client process.  The
server creates and binds a socket to a port that dynamically allocated,
listen on it, and start a infinite loop.  Inside the loop, it accepts
connection, reads 4 bytes from the socket, and closes the connection.
The client is constructed as an infinite loop.  Inside the loop, it
creates a socket with LINGER and NODELAY option, connect to the server,
send 4 bytes data, try read some data from server.  After the read()
returns, it measure the latency from the beginning of this loop to this
point and if the latency is larger than 1 second (spike), print a
message.

The function busywait() is handy as a safety-latched variant of a while
loop. Many selftests deal specifically with counter values, and busywaiting
on them is likely to be rather common (it is not quite common now, but
busywait() has not been around for very long). To facilitate expressing
simply what is tested, introduce two helpers:

- until_counter_is(), which can be used as a predicate passed to
  busywait(), which holds when expression, which is itself passed as an
  argument to until_counter_is(), reaches a desired value.

- busywait_for_counter(), which is useful for waiting until a given counter
  changes "by" (as opposed to "to") a certain amount.

048d19d444 mptcp: add basic kselftest for mptcp
Add mptcp_connect tool:
xmit two files back and forth between two processes, several net
namespaces including some adding delays, losses and reordering.
Wrapper script tests that data was transmitted without corruption.

The "-c" command line option for mptcp_connect.sh is there for debugging:

The script will use tcpdump to create one .pcap file per test case, named
according to the namespaces, protocols, and connect address in use.
For example, the first test case writes the capture to
ns1-ns1-MPTCP-MPTCP-10.0.1.1.pcap.

The stderr output from tcpdump is printed after the test completes to
show tcpdump's "packets dropped by kernel" information.

Also check that userspace can't create MPTCP sockets when mptcp.enabled
sysctl is off.

The "-b" option allows to tune/lower send buffer size.
"-m mmap" can be used to test blocking io.  Default is non-blocking
io using read/write/poll.

Will run automatically on "make kselftest".

Note that the default timeout of 45 seconds is used even if there is a
"settings" changing it to 450. 45 seconds should be enough in most cases
but this depends on the machine running the tests.

A fix to correctly read the "settings" file has been proposed upstream
but not applied yet. It is not blocking the execution of these new tests
but it would be nice to have it:

17aa23ee72 fcnal-test: Fix vrf argument in local tcp tests
The recent MD5 tests added duplicate configuration in the default VRF.
This change exposed a bug in existing tests designed to verify no
connection when client and server are not in the same domain. The
server should be running bound to the vrf device with the client run
in the default VRF (the -2 option is meant for validating connection
data). Fix the option for both tests.

While technically this is a bug in previous releases, the tests are
properly failing since the default VRF does not have any routing
configuration so there really is no need to backport to prior releases.

ddd3fd750f selftests: forwarding: sch_ets: Add test coverage for ETS Qdisc
This tests the newly-added ETS Qdisc. It runs two to three streams of
traffic, each with a different priority. ETS Qdisc is supposed to allocate
bandwidth according to the DRR algorithm and given weights. After running
the traffic for a while, counters are compared for each stream to check
that the expected ratio is in fact observed.

In order for the DRR process to kick in, a traffic bottleneck must exist in
the first place. In slow path, such bottleneck can be implemented by
wrapping the ETS Qdisc inside a TBF or other shaper. This might however
make the configuration unoffloadable. Instead, on HW datapath, the
bottleneck would be set up by lowering port speed and configuring shared
buffer suitably.

Therefore the test is structured as a core component that implements the
testing, with two wrapper scripts that implement the details of slow path
resp. fast path configuration.

ea6a547669 selftests/net: make so_txtime more robust to timer variance
The SO_TXTIME test depends on accurate timers. In some virtualized
environments the test has been reported to be flaky. This is easily
reproduced by disabling kvm acceleration in Qemu.

Allow greater variance in a run and retry to further reduce flakiness.

Observed errors are one of two kinds: either the packet arrives too
early or late at recv(), or it was dropped in the qdisc itself and the
recv() call times out.

In the latter case, the qdisc queues a notification to the error
queue of the send socket. Also explicitly report this cause.

TEST: ipv6: list and flush cached exceptions                        [FAIL]
  can't list cached exceptions

That happens, for example, with iproute2 4.15.0. When using the -oneline
option, this will work just fine:

TEST: ipv6: list and flush cached exceptions                        [ OK ]

This also works just fine with a more recent version of iproute2, like
5.4.0.

For some reason, two lines are printed for the IPv4 test no matter what
version of iproute2 is used. Use the same -oneline parameter there instead
of counting the lines twice.

        /usr/include/linux/ethtool.h The array looks as follows:
	[10baseT/Half] = 0,
	[10baseT/Full] = 1,
	...

2. ethtool_set:
	params: cmd
	The function runs ethtool by cmd (ethtool -s cmd) and checks if
	there was an error in configuration

3. dev_speeds_get:
	params: dev, with_mode (0 or 1), adver (0 or 1)
	return value: Array of supported/Advertised link modes
	with/without mode

	* Example 1:
	speeds_get swp1 0 0
	return: 1000 10000 40000
	* Example 2:
	speeds_get swp1 1 1
	return: 1000baseKX/Full 10000baseKR/Full 40000baseCR4/Full

4. common_speeds_get:
	params: dev1, dev2, with_mode (0 or 1), adver (0 or 1)
	return value: Array of common speeds of dev1 and dev2

	* Example:
	common_speeds_get swp1 swp2 0 0
	return: 1000 10000
	Assuming that swp1 supports 1000 10000 40000 and swp2 supports
	1000 10000

597b01edaf selftests: net: avoid ptl lock contention in tcp_mmap
tcp_mmap is used as a reference program for TCP rx zerocopy,
so it is important to point out some potential issues.

If multiple threads are concurrently using getsockopt(...
TCP_ZEROCOPY_RECEIVE), there is a chance the low-level mm
functions compete on shared ptl lock, if vma are arbitrary placed.

Instead of letting the mm layer place the chunks back to back,
this patch enforces an alignment so that each thread uses
a different ptl lock.

Performance measured on a 100 Gbit NIC, with 8 tcp_mmap clients
launched at the same time :

$ for f in {1..8}; do ./tcp_mmap -H 2002:a05:6608:290:: & done

In the following run, we reproduce the old behavior by requesting no alignment :

$ tcp_mmap -sz -C $((128*1024)) -a 4096

                ----
                |H1|

where H1's default route goes through R1 and R1's default route goes
through R2 over N2, traceroute6 from H1 to H2 reports R2's address
on N2 and not N1.

IPV4:
Verify that traceroute from H1 to H2 shows 1.0.1.1 in this scenario

                   1.0.3.1/24
---- 1.0.1.3/24    1.0.1.1/24 ---- 1.0.2.1/24    1.0.2.4/24 ----
|H1|--------------------------|R1|--------------------------|H2|
----            N1            ----            N2            ----

where net.ipv4.icmp_errors_use_inbound_ifaddr is set on R1 and
1.0.3.1/24 and 1.0.1.1/24 are respectively R1's primary and secondary
address on N1.

enabling UDP GSO would fail if the system had SW GSO enabled, but the
same send would succeed if HW GSO offload is enabled. In addition to this
inconsistency the error in the SW GSO case does not get back to the
application if sending out of a real device so the user is unaware of this
failure.

With this change we only perform GSO if the # of segments is > 1 even

was triggered by WireGuard users who use wg-quick(8), which uses the
"suppress-prefix" directive to ip-rule(8) for routing all of their
internet traffic without routing loops. The test case added here
causes the reference underflow by causing packets to evaluate a suppress

Cleanups of the tests in fib_nexthops.sh
1. Several tests noted unexpected route output, but the
   discrepancy was not showing in the summary output and
   overlooked in the verbose output. Add a WARNING message
   to the summary output to make it clear a test is not showing
   expected output.

2. Several check_* calls are missing extra data like scope and metric
   causing mismatches when the nexthops or routes are correct - some of
   them are a side effect of the evolving iproute2 command. Update the
   data to the expected output.

3. Several check_routes are checking for the wrong nexthop data,
   most likely a copy-paste-update error.

4. A couple of tests were re-using a nexthop id that already existed.

There is no reproducer, however, the warning can be reproduced
by adding rules with ever smaller prefixes.

The sanity check ("does the policy match the node") uses the prefix value
of the node before its updated to the smaller value.

To fix this, update the prefix earlier.  The bug has no impact on tree
correctness, this is only to prevent a false warning.

87caaaf2d1 selftests: Fix get_ifidx and callers in nettest.c
Dan reported:

    The patch acda655fef: "selftests: Add nettest" from Aug 1, 2019,
    leads to the following static checker warning:

            ./tools/testing/selftests/net/nettest.c:1690 main()
            warn: unsigned 'tmp' is never less than zero.

    ./tools/testing/selftests/net/nettest.c
      1680                  case '1':
      1681                          args.has_expected_raddr = 1;
      1682                          if (convert_addr(&args, optarg,
      1683                                           ADDR_TYPE_EXPECTED_REMOTE))
      1684                                  return 1;
      1685
      1686                          break;
      1687                  case '2':
      1688                          if (str_to_uint(optarg, 0, 0x7ffffff, &tmp) != 0) {
      1689                                  tmp = get_ifidx(optarg);
      1690                                  if (tmp < 0) {

    "tmp" is unsigned so it can't be negative.  Also all the callers assume
    that get_ifidx() returns negatives on error but it looks like it really
    returns zero on error so it's a bit unclear to me.

Update get_ifidx to return -1 on errors and cleanup callers of it.

acda655fef selftests: Add nettest
Add nettest - a simple program with an implementation for various networking
APIs. nettest is used for tcp, udp and raw functional tests for both IPv4
and IPv6.

Point of this command versus existing utilities:
- controlled implementation of the APIs and the order in which they
  are called,
- ability to verify ingress device, local and remote addresses,
- timeout for controlled test length,
- ability to discriminate a timeout from a system call failure, and
- simplicity with test scripts.

The command returns:
  0  on success,
  1  for any system call failure, and
  2  on timeout.

The TC filters used in the test do not work with veth devices because the
outer Ethertype is 802.1Q and not IPv4. The test passes with mlxsw
netdevs since the hardware always looks at "The first Ethertype that
does not point to either: VLAN, CNTAG or configurable Ethertype".

Fix this by matching on the VLAN ID instead, but on the ingress side.
The reason why this is not performed at egress is explained in the
commit cited below.

 setup_net+0x212/0x690 net/core/net_namespace.c:316

The faulting address is the address of the old chain head,
free'd by xfrm_hash_resize().

In xfrm_hash_rehash(), chain heads get re-initialized without
any hlist_del_rcu:

 for (i = hmask; i >= 0; i--)
    INIT_HLIST_HEAD(odst + i);

Then, hlist_del_rcu() gets called on the about to-be-reinserted policy
when iterating the per-net list of policies.

hlist_del_rcu() will then make chain->first be nonzero again:

static inline void __hlist_del(struct hlist_node *n)
{
   struct hlist_node *next = n->next;   // address of next element in list
   struct hlist_node **pprev = n->pprev;// location of previous elem, this
                                        // can point at chain->first
        WRITE_ONCE(*pprev, next);       // chain->first points to next elem
        if (next)
                next->pprev = pprev;

Then, when we walk chainlist to find insertion point, we may find a
non-empty list even though we're supposedly reinserting the first
policy to an empty chain.

To fix this first unlink all exact and inexact policies instead of
zeroing the list heads.

Add the commands equivalent to the syzbot reproducer to xfrm_policy.sh,
without fix KASAN catches the corruption as it happens, SLUB poisoning
detects it a bit later.

ff95bf28c2 selftests/net: skip psock_tpacket test if KALLSYMS was not enabled
The psock_tpacket test will need to access /proc/kallsyms, this would
require the kernel config CONFIG_KALLSYMS to be enabled first.

Apart from adding CONFIG_KALLSYMS to the net/config file here, check the
file existence to determine if we can run this test will be helpful to
avoid a false-positive test result when testing it directly with the
following commad against a kernel that have CONFIG_KALLSYMS disabled:

b964641e99 selftests: pmtu: Make list_flush_ipv6_exception test more demanding
Instead of just listing and flushing two cached exceptions, create
a relatively big number of them, and count how many are listed. Single
netlink dump messages contain approximately 25 entries each, and this
way we can make sure the partial dump tracking mechanism is working
properly.

While at it, also ensure that no cached routes can be listed after
flush, and remove 'sleep 1' calls, they are not actually needed.

22f1a38a54 selftests/net: make udpgso_bench skip unsupported testcases
Kselftest can be run against older kernels. Instead of failing hard
when a feature is unsupported, return the KSFT_SKIP exit code.

Specifically, do not fail hard on missing udp zerocopy.

The udp gso bench test runs multiple test cases from a single script.
Fail if any case fails, else return skip if any test is skipped.

ade90d69ff net/udpgso_bench.sh add UDP GSO audit tests
Audit tests count the total number of messages sent and compares
with total number of CMSG received on error queue. Example:

    udp gso zerocopy timestamp audit
    udp rx:   1599 MB/s  1166414 calls/s
    udp tx:   1615 MB/s    27395 calls/s  27395 msg/s
    udp rx:   1634 MB/s  1192261 calls/s
    udp tx:   1633 MB/s    27699 calls/s  27699 msg/s
    udp rx:   1633 MB/s  1191358 calls/s
    udp tx:   1631 MB/s    27678 calls/s  27678 msg/s
    Summary over 4.000 seconds...
    sum udp tx:   1665 MB/s      82772 calls (27590/s)      82772 msgs (27590/s)
    Tx Timestamps:               82772 received                 0 errors
    Zerocopy acks:               82772 received

Errors are thrown if CMSG count does not equal send count,
example:

    Summary over 4.000 seconds...
    sum tcp tx:   7451 MB/s     493706 calls (123426/s)     493706 msgs (123426/s)
    ./udpgso_bench_tx: Unexpected number of Zerocopy completions:    493706 expected    493704 received

Also reduce individual test time from 4 to 3 seconds so that
overall test time does not increase significantly.

79ebc3c260 net/udpgso_bench_tx: options to exercise TX CMSG
This enhancement adds options that facilitate load testing with
additional TX CMSG options, and to optionally print results of
various send CMSG operations.

These options are especially useful in isolating situations
where error-queue messages are lost when combined with other
CMSG operations (e.g. SO_ZEROCOPY).

New options:
    -a - count all CMSG messages and match to sent messages
    -T - add TX CMSG that requests TX software timestamps
    -H - similar to -T except request TX hardware timestamps
    -P - call poll() before reading error queue
    -v - print detailed results

v2: Enhancements as per Willem de Bruijn <willemb@google.com>
    - Updated control and buffer parameters for recvmsg
    - poll() parameter cleanup
    - fail on bad audit results
    - remove TOS options
    - improved reporting

v3: Enhancements as per Willem de Bruijn <willemb@google.com>
    - add SOF_TIMESTAMPING_OPT_TSONLY to eliminate MSG_TRUNC
    - general code cleanup

67c0aaa1ea selftests: set sysctl bc_forwarding properly in router_broadcast.sh
sysctl setting bc_forwarding for $rp2 is needed when ping_test_from h2,
otherwise the bc packets from $rp2 won't be forwarded. This patch is to
add this setting for $rp2.

Also, as ping_test_from does grep "$from" only, which could match some
unexpected output, some test case doesn't really work, like:

  # ping_test_from $h2 198.51.200.255 198.51.200.2
    PING 198.51.200.255 from 198.51.100.2 veth3: 56(84) bytes of data.
    64 bytes from 198.51.100.1: icmp_seq=1 ttl=64 time=0.336 ms

When doing grep $form (198.51.200.2), the output could still match.
So change to grep "bytes from $from" instead.

73f51d151e selftests: pmtu: Fix encapsulating device in pmtu_vti6_link_change_mtu
In the pmtu_vti6_link_change_mtu test, both local and remote addresses
for the vti6 tunnel are assigned to the same address given to the dummy
interface that we use as encapsulating device with a known MTU.

This works as long as the dummy interface is actually selected, via
rt6_lookup(), as encapsulating device. But if the remote address of the
tunnel is a local address too, the loopback interface could also be
selected, and there's nothing wrong with it.

This is what some older -stable kernels do (3.18.z, at least), and
nothing prevents us from subtly changing FIB implementation to revert
back to that behaviour in the future.

Define an IPv6 prefix instead, and use two separate addresses as local
and remote for vti6, so that the encapsulating device can't be a
loopback interface.

99513cfa16 selftest: Fixes for icmp_redirect test
I was really surprised that the IPv6 mtu exception followed by redirect
test was passing as nothing about the code suggests it should. The problem
is actually with the logic in the test script.

Fix the test cases as follows:
1. add debug function to dump the initial and redirect gateway addresses
   for ipv6. This is shown only in verbose mode. It helps verify the
   output of 'route get'.

2. fix the check_exception logic for the reset case to make sure that
   for IPv4 neither mtu nor redirect appears in the 'route get' output.
   For IPv6, make sure mtu is not present and the gateway is the initial
   R1 lladdr.

3. fix the reset logic by using a function to delete the routes added by
   initial_route_*. This format works better for the nexthop version of
   the tests.

While improving the test cases, go ahead and ensure that forwarding is
disabled since IPv6 redirect requires it.

Also, runs with kernel debugging enabled sometimes show a failure with
one of the ipv4 tests, so spread the pings over longer time interval.

The end result is that 2 tests now show failures:

TEST: IPv6: mtu exception plus redirect                    [FAIL]

and the VRF version.

This is a bug in the IPv6 logic that will need to be fixed
separately. Redirect followed by MTU works because __ip6_rt_update_pmtu
hits the 'if (!rt6_cache_allowed_for_pmtu(rt6))' path and updates the
mtu on the exception rt6_info.

MTU followed by redirect does not have this logic. rt6_do_redirect
creates a new exception and then rt6_insert_exception removes the old
one which has the MTU exception.

af5136f950 selftests/net: SO_TXTIME with ETF and FQ
The SO_TXTIME API enables packet tranmission with delayed delivery.
This is currently supported by the ETF and FQ packet schedulers.

Evaluate the interface with both schedulers. Install the scheduler
and send a variety of packets streams: without delay, with one
delayed packet, with multiple ordered delays and with reordering.
Verify that packets are released by the scheduler in expected order.

The ETF qdisc requires a timestamp in the future on every packet. It
needs a delay on the qdisc else the packet is dropped on dequeue for
having a delivery time in the past. The test value is experimentally
derived. ETF requires clock_id CLOCK_TAI. It checks this base and
drops for non-conformance.

The FQ qdisc expects clock_id CLOCK_MONOTONIC, the base used by TCP
as of commit fb420d5d91 ("tcp/fq: move back to CLOCK_MONOTONIC").
Within a flow there is an expecation of ordered delivery, as shown by
delivery times of test 4. The FQ qdisc does not require all packets to
have timestamps and does not drop for non-conformance.

The large (msec) delays are chosen to avoid flakiness.

	Output:

	SO_TXTIME ipv6 clock monotonic
	payload:a delay:28 expected:0 (us)

	SO_TXTIME ipv4 clock monotonic
	payload:a delay:38 expected:0 (us)

	SO_TXTIME ipv6 clock monotonic
	payload:a delay:40 expected:0 (us)

	SO_TXTIME ipv4 clock monotonic
	payload:a delay:33 expected:0 (us)

	SO_TXTIME ipv6 clock monotonic
	payload:a delay:10120 expected:10000 (us)

	SO_TXTIME ipv4 clock monotonic
	payload:a delay:10102 expected:10000 (us)

	[.. etc ..]

	OK. All tests passed
