63f3c1d06f selftests: mlxsw: RED: Test RED ECN nodrop offload
Extend RED testsuite to cover the new nodrop mode of RED-ECN. This test is
really similar to ECN test, diverging only in the last step, where UDP
traffic should go to backlog instead of being dropped. Thus extract a
common helper, ecn_test_common(), make do_ecn_test() into a relatively
simple wrapper, and add another one, do_ecn_nodrop_test().

b9b72999eb selftests: forwarding: ETS: Use Qdisc counters
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.

e781eedae2 selftests: mlxsw: Reduce router scale running time using offload indication
Currently, the test inserts X /32 routes and for each route it is
testing that a packet sent from the first host is received by the second
host, which is very time-consuming.

Instead only validate the offload flag of each route and get the same result.

Wait between the creation of the routes and the offload validation in
order to make sure that all the routes were successfully offloaded.

5d66773f41 selftests: devlink_trap_l3_drops: Avoid race condition
The test checks that packets are trapped when they should egress a
router interface (RIF) that has become disabled. This is a temporary
state in a RIF's deletion sequence.

Currently, the test deletes the RIF by flushing all the IP addresses
configured on the associated netdev (br0). However, this is racy, as
this also flushes all the routes pointing to the netdev and if the
routes are deleted from the device before the RIF is disabled, then no
packets will try to egress the disabled RIF and the trap will not be
triggered.

Instead, trigger the deletion of the RIF by unlinking the mlxsw port
from the bridge that is backing the RIF. Unlike before, this will not
cause the kernel to delete the routes pointing to the bridge.

Note that due to current mlxsw locking scheme the RIF is always deleted
first, but this is going to change.

745a7ea72d selftests: mlxsw: Remove deprecated test
The addition of a VLAN on a bridge slave prompts the driver to have the
local port in question join the FID corresponding to this VLAN.

Before recent changes, the operation of joining the FID would also mean
that the driver would enable VXLAN tunneling if a VXLAN device was also
member in the VLAN. In case the configuration of the VXLAN tunnel was
not supported, an extack error would be returned.

Since the operation of joining the FID no longer means that VXLAN
tunneling is potentially enabled, the test is no longer relevant. Remove
it.

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.

4d189c1026 selftests: mlxsw: Adjust test to recent changes
mlxsw does not support VXLAN devices with a physical device attached and
vetoes such configurations upon enslavement to an offloaded bridge.

Commit 0ce1822c2a ("vxlan: add adjacent link to limit depth level")
changed the VXLAN device to be an upper of the physical device which
causes mlxsw to veto the creation of the VXLAN device with "Unknown
upper device type".

This is OK as this configuration is not supported, but it prevents us
from testing bad flows involving the enslavement of VXLAN devices with a
physical device to a bridge, regardless if the physical device is an
mlxsw netdev or not.

Adjust the test to use a dummy device as a physical device instead of a
mlxsw netdev.

979b9b251a mlxsw: spectrum: Clear VLAN filters during port initialization
When a port is created, its VLAN filters are not cleared by the
firmware. This causes tagged packets to be later dropped by the ingress
STP filters, which default to DISCARD state.

The above did not matter much until commit b5ce611fd9 ("mlxsw:
spectrum: Add devlink-trap support") where we exposed the drop reason to
users.

Without this patch, the drop reason users will see is not consistent. If
a port is enslaved to a VLAN-aware bridge and a packet with an invalid
VLAN tries to ingress the bridge, it will be dropped due to ingress STP
filter. If the VLAN is later enabled and then disabled, the packet will
be dropped by the ingress VLAN filter despite the above being a
seemingly NOP operation.

Fix this by clearing all the VLAN filters during port initialization.
Adjust the test accordingly.

   to be reused between "run_tests" and "emit_tests", while also fixing

 	- fixed result line syntax
 	- moved all test output to be "# "-prefixed as TAP "diagnostic"
 	  lines
 
   The prefixing code includes a fallback mode for limited execution
   environments.
 
   Additionally, the plan lines are fixed for all callers of kselftest.h.

   TAP13 compliant from Kees Cook:

   This re-factors the selftest Makefiles to extract the test running
   logic to be reused between "run_tests" and "emit_tests", while also
   fixing up the test output to be TAP version 13 compliant:
	- added "plan" line
	- fixed result line syntax
	- moved all test output to be "# "-prefixed as TAP "diagnostic"
	  lines

   The prefixing code includes a fallback mode for limited execution
   environments.

   Additionally, the plan lines are fixed for all callers of
   kselftest.h.

5dde21b3a7 selftests: mlxsw: qos_mc_aware: Configure shared buffers
This test runs two streams of traffic from two independent ports to
create congestion on one egress port. It is necessary to configure the
shared buffer thresholds correctly, to make sure that there is traffic
from both streams in the shared buffer. Only then can the test actually
test prioritization among these streams.

Without this configuration, it is possible, that one of the streams
takes all of port-pool quota, and the other stream is not even admitted,
thus invalidating the result.

On Spectrum-1, this is not a problem, because MC traffic uses a separate
pool. But for Spectrum-2, MC and UC share the same pool, and the correct
configuration is important.

f3b05bb819 selftests: mlxsw: 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. This
traffic is seen at the counters, and causes spurious failures.

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