4cf9b8f992 selftests: forwarding: Move start_/stop_traffic from mlxsw to lib.sh
These two functions are used for starting several streams of traffic, and
then stopping them later. They will be handy for the test coverage of ETS
Qdisc. Move them from mlxsw-specific qos_lib.sh to the generic lib.sh.

65cb139862 selftests: forwarding: Delete IPv6 address at the end
When creating the second host in h2_create(), two addresses are assigned
to the interface, but only one is deleted. When running the test twice
in a row the following error is observed:

$ ./router_bridge_vlan.sh
TEST: ping                                                          [ OK ]

64916b57c0 selftests: forwarding: Add speed and auto-negotiation test
Check configurations and packets transference with different variations
of autoneg and speed.

Test plan:
1. Test force of same speed with autoneg off
2. Test force of different speeds with autoneg off (should fail)
3. One side is autoneg on and other side sets force of common speeds
4. One side is autoneg on and other side only advertises a subset of the
   common speeds (one speed of the subset)
5. One side is autoneg on and other side only advertises a subset of the
   common speeds. Check that highest speed is negotiated
6. Test autoneg on, but each side advertises different speeds (should
   fail)

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.

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.

35036b0b09 selftests: forwarding: mirror_gre_vlan_bridge_1q: Fix untagged test
The untagged egress test sets up mirroring to {,ip6}gretap such that the
underlay goes through a bridge. Then VLAN flags are manipulated to test
that the traffic leaves the bridge 802.1q-tagged or not, as appropriate.

However, when a neighbor expires at the time that the bridge VLAN is
configured as PVID and egress untagged, the following discovery process
can't finish, because the IP address on H3 is still at the VLAN-tagged
netdevice. This manifests by occasional failures where only several of
the 10 required packets get through.

Therefore, when reconfiguring the VLAN flags, move the IP address to the
appropriate device in the H3 VRF.

In addition to that, take this opportunity to embed an ASCII art diagram
to make the topology move obvious.

0175cb5922 selftests: forwarding: mirror_lib: Update ping limits
The current ping intervals are too short for running mirroring tests in
simulator. This leads to ping sending a follow-up ping before the reply
arrives, thus sending more than the requested 10 ICMP requests. Those
are mirrored, and over a certain threshold the test case run is
considered a failure, because too much traffic is observed.

Bump interval and timeout numbers 5x in mirroring tests to address the
spurious failures.

4dba72fd3e selftests: forwarding: Add a test case for ARP suppression
ARP suppression allows the Linux bridge to answer ARP requests on behalf
of remote hosts. It reduces the amount of packets a VTEP needs to flood.

This test verifies that ARP suppression on / off works when a neighbour
exists and when it does not exist. It does so by sending an ARP request
from a host connected to one VTEP and checking whether it was received
by a second VTEP.

289fb44df4 selftests: forwarding: Fix test for different devices
When running the test on the Spectrum ASIC the generated packets are
counted on the ingress filter and injected back to the pipeline because
of the 'pass' action. The router block then drops the packets due to
checksum error, as the test generates packets with zero checksum.

When running the test on an emulator that is not as strict about
checksum errors the test fails since packets are counted twice. Once by
the emulated ASIC on its ingress filter and again by the kernel as the
emulator does not perform checksum validation and allows the packets to
be trapped by a matching host route.

Fix this by changing the action to 'drop', which will prevent the packet
from continuing further in the pipeline to the router block.

For veth pairs this change is essentially a NOP given packets are only
processed once (by the kernel).

In order to run a certain command inside another network namespace, it's
possible to use "ip netns exec ns command". However then one can't use

One option is to do "ip netns exec ns bash -c command", provided that
all functions that one wishes to use (and their dependencies) are
published using "export -f". That may not be practical.

Therefore, introduce a helper in_ns(), which wraps a given command in a
boilerplate of "ip netns exec" and "source lib.sh", thus making all
library functions available. (Custom functions that a script wishes to
run within a namespace still need to be exported.)

setup_wait() and tc_offload_check() both assume that all NUM_NETIFS
interfaces are relevant for a given test. However, the scale test script
acts as an umbrella for a number of sub-tests, some of which may not
require all the interfaces.

Thus it's suboptimal for tc_offload_check() to query all the interfaces.
In case of setup_wait() it's incorrect, because the sub-test in question
of course doesn't configure any interfaces beyond what it needs, and
setup_wait() then ends up waiting indefinitely for the extraneous
interfaces to come up.

For that reason, give setup_wait() and tc_offload_check() an optional
parameter with a number of interfaces to probe. Fall back to global
NUM_NETIFS if the parameter is not given.

275225fb4e selftests: forwarding: mirror_lib: skip_hw the VLAN capture
When the VLAN capture is installed on a front panel device and not a
soft device, the packets are counted twice: once in fast path, and once
after they are trapped to the kernel. Resolve the problem by passing
skip_hw flag to vlan_capture_install().

For non-GRE mirroring tests, a functions along the lines of

from mirror_gre_lib.sh to mirror_lib.sh and convert to just use a given
device without assuming it's named "h3-$tundev". Convert the two
above-mentioned functions to wrappers that pass along the correct device
name.

9413248753 selftests: forwarding: Increase maximum deviation in multipath test
We sometimes observe failures in the test due to too large discrepancy
between the measured and expected ratios. For example:

TEST: ECMP                                                          [FAIL]
        Too large discrepancy between expected and measured ratios
        INFO: Expected ratio 1.00 Measured ratio 1.11

Fix this by allowing an up to 15% deviation between both ratios.

Another possibility is to increase the number of generated flows, but
this will prolong the execution time of the test, which is already quite
high.
