    Description

      We would like to get clarification and verify configuration using patch LU-3322.

      We are running 2.7.2 with patch from LU-3322. When configureing two hosts with different peer_credits we get this error when the initial connection is made.

      LNetError: 81:0:(o2iblnd_cb.c:2325:kiblnd_passive_connect()) Can't accept conn from xxx.xxx.xxx.xxx@o2ib, queue depth too large:  63 (<=16 wanted)
      

      Although we get the error lnet_selftest is working.

      Host1:

      options ko2iblnd timeout=150 retry_count=7 peer_timeout=0 peer_credits=63 concurrent_sends=63
      

      Host2

      options ko2iblnd timeout=150 retry_count=7 peer_credits=16 concurrent_sends=63
      

      Attaching debug output from HOST2
