selftests: mlxsw: Add test cases for devlink-trap policers

2020-03-31T00:54:59+00:00

Add test cases that verify that each registered packet trap policer:

* Honors that imposed limitations of rate and burst size
* Able to police trapped packets to the specified rate
* Able to police trapped packets to the specified burst size
* Able to be unbound from its trap group

selftests: netdevsim: Add test cases for devlink-trap policers

2020-03-31T00:54:59+00:00

Add test cases for packet trap policer set / show commands as well as
for the binding of these policers to packet trap groups.

Both good and bad flows are tested for maximum coverage.

v2:
* Add test case with new 'fail_trap_policer_set' knob
* Add test case for partially modified trap group

netdevsim: Change dummy reporter auto recover default

2020-03-30T18:17:34+00:00

Health reporters should be registered with auto recover set to true.
Align dummy reporter behaviour with that, as in later patch the option to
set auto recover behaviour will be removed.

In addition, align netdevsim selftest to the new default value.

netdevsim: support taking immediate snapshot via devlink

2020-03-27T02:39:26+00:00

Implement the .snapshot region operation for the dummy data region. This
enables a region snapshot to be taken upon request via the new
DEVLINK_CMD_REGION_SNAPSHOT command.

selftests: mlxsw: qos_dscp_router: Test no DSCP rewrite after pedit

2020-03-26T18:55:40+00:00

When DSCP is updated through an offloaded pedit action, DSCP rewrite on
egress should be disabled. Add a test that check that it is so.

selftests: spectrum-2: Adjust tc_flower_scale limit according to current counter count

2020-03-18T23:46:19+00:00

With the change that made the code to query counter bank size from device
instead of using hard-coded value, the number of available counters
changed for Spectrum-2. Adjust the limit in the selftests.

selftests: mlxsw: RED: Test RED ECN nodrop offload

2020-03-15T04:03:46+00:00

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().

selftests: forwarding: ETS: Use Qdisc counters

2020-03-05T22:03:32+00:00

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.

selftests: mlxsw: qos_defprio: Use until_counter_is

Instead of hand-coding the busywait() predicate, use the until_counter_is()
introduced recently.
