selftests: ocelot: tc_flower_chains: reorder interfaces

2022-05-22T21:14:13Z

Use the standard interface order h1, swp1, swp2, h2 that is used by the forwarding selftest framework. The previous order was confusing even with the ASCII drawing. That isn't needed anymore. This also drops the fixed MAC addresses and uses STABLE_MAC_ADDRS, which ensures the MAC addresses are unique. Signed-off-by: Vladimir Oltean Signed-off-by: David S. Miller

selftests: ocelot: tc_flower_chains: use conventional interface names

2022-05-22T21:14:13Z

This is a robotic rename as follows: eth0 -> swp1 eth1 -> swp2 eth2 -> h2 eth3 -> h1 This brings the selftest more in line with the other forwarding selftests, where h1 is connected to swp1, and h2 to swp2. Signed-off-by: Vladimir Oltean Signed-off-by: David S. Miller

selftests: netdevsim: Increase sleep time in hw_stats_l3.sh test

2022-05-18T13:06:50Z

hw_stats_l3.sh test is failing often for l3 stats shows less than 20 packets after 2 seconds sleep. This is happening since there is a race between the 2 seconds sleep and the netdevsim actually delivering the packets. Increase the sleep time so the packets will be delivered successfully on time.

selftests: ocelot: tc_flower_chains: specify conform-exceed action for policer

2022-05-05T02:40:19Z

As discussed here with Ido Schimmel: https://patchwork.kernel.org/project/netdevbpf/patch/20220224102908.5255-2-jianbol@nvidia.com/ the default conform-exceed action is "reclassify", for a reason we don't really understand. The point is that hardware can't offload that police action, so not specifying "conform-exceed" was always wrong, even though the command used to work in hardware (but not in software) until the kernel started adding validation for it. Fix the command used by the selftest by making the policer drop on exceed, and pass the packet to the next action (goto) on conform.

selftests: mlxsw: bail_on_lldpad before installing the cleanup trap

2022-05-04T10:21:32Z

A number of mlxsw-specific QoS tests use manual QoS DCB management. As such, they need to make sure lldpad is not running, because it would override the configuration the test has applied using other tools. To that end, these selftests invoke the bail_on_lldpad() helper, which terminates the selftest if th lldpad is running. Some of these tests however first install the bash exit trap, which invokes a cleanup() at the test exit. If bail_on_lldpad() has terminated the script even before the setup part was run, the cleanup part will be very confused. Therefore make sure bail_on_lldpad() is invoked before the cleanup is registered. While there are still edge cases where the user terminates the script before the setup was fully done, this takes care of a common situation where the cleanup would be invoked in an inconsistent state.
