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: netdevsim: Always initialize 'RET' variable

2020-05-22T23:05:42Z

The variable is used by log_test() to check if the test case completely successfully or not. In case it is not initialized at the start of a test case, it is possible for the test case to fail despite not encountering any errors. Example: ``` ... TEST: Trap group statistics [ OK ] TEST: Trap policer [FAIL] Policer drop counter was not incremented TEST: Trap policer binding [FAIL] Policer drop counter was not incremented ``` Failure of trap_policer_test() caused trap_policer_bind_test() to fail as well. Fix by adding missing initialization of the variable.

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: netdevsim: Add test cases for devlink-trap policers

2020-03-31T00:54:59Z

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

netdevsim: Change dummy reporter auto recover default

2020-03-30T18:17:34Z

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. Signed-off-by: Eran Ben Elisha Reviewed-by: Jiri Pirko Signed-off-by: David S. Miller

netdevsim: support taking immediate snapshot via devlink

2020-03-27T02:39:26Z

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. Signed-off-by: Jacob Keller Reviewed-by: Jiri Pirko Signed-off-by: David S. Miller

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

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.
