Description Brian Chae 2022-11-28 11:34:27 UTC

Description of problem:

"sockperf pingpong multicast pkey/vlan" test case consistently fails when libvma is tested on MLX5 IB0 devices.

Checking for failures and known issues:
  sockperf pingpong multicast pkey/vlan is NOT a known issue on any environment - consider filing a BZ

           ++++++++++++++++++++++

This is a regression where, with RHEL-8.7.0, the same test passes.

Steps to Reproduce:

+ [22-11-28 04:34:27] export SERVER_IP2=172.31.2.182
+ [22-11-28 04:34:27] SERVER_IP2=172.31.2.182

1. Get both RDMA server & client hosts ready for libvma test with current sockperf, with RHEL-8.8 build as specified above on MLX4 IB0 devices
2. On server host, issue the following commands

LD_PRELOAD=libvma.so
timeout --preserve-status --kill-after=5m 3m sockperf server -i 172.31.2.182

3. On the client hosts, issue the following command

LD_PRELOAD=libvma.so
timeout --preserve-status --kill-after=5m 3m sockperf pp -i 172.31.2.182 -t 10 --msg-size=1472
