selftests: mlxsw: qos_mc_aware: Specify arping timeout as an integer

2020-05-22T23:08:14Z

Starting from iputils s20190709 (used in Fedora 31), arping does not support timeout being specified as a decimal: $ arping -c 1 -I swp1 -b 192.0.2.66 -q -w 0.1 arping: invalid argument: '0.1' Previously, such timeouts were rounded to an integer. Fix this by specifying the timeout as an integer.

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

2020-03-31T00:54:59Z

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 Signed-off-by: Ido Schimmel Signed-off-by: David S.

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

2020-03-26T18:55:40Z

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. Signed-off-by: Petr Machata Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

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

2020-03-18T23:46:19Z

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. Signed-off-by: Jiri Pirko Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

selftests: mlxsw: RED: Test RED ECN nodrop offload

2020-03-15T04:03:46Z

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(). Signed-off-by: Petr Machata Signed-off-by: David S.

selftests: forwarding: ETS: Use Qdisc counters

2020-03-05T22:03:32Z

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. Signed-off-by: Petr Machata Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

selftests: mlxsw: qos_defprio: Use until_counter_is

2020-03-04T01:03:52Z

Instead of hand-coding the busywait() predicate, use the until_counter_is() introduced recently. Signed-off-by: Petr Machata Reviewed-by: Amit Cohen Signed-off-by: David S. Miller

selftests: forwarding: Convert until_counter_is() to take expression

2020-03-04T01:03:52Z

until_counter_is() currently takes as an argument a number and the condition holds when the current counter value is >= that number. Make the function more generic by taking a partial expression instead of just the number. Convert the two existing users. Signed-off-by: Petr Machata Reviewed-by: Amit Cohen Signed-off-by: David S.
