Subject: [PATCH 1/1] RDMA/irdma: Increase iWARP CM default rexmit count
Git-commit: 8385a875c9eecc429b2f72970efcbb0e5cb5b547
Patch-mainline: v6.3-rc7
References: git-fixes
When running perftest with large number of connections in iWARP mode, the
passive side could be slow to respond. Increase the rexmit counter default
to allow scaling connections.
Fixes: 146b9756f14c ("RDMA/irdma: Add connection manager")
