From 36ac0db0dbf7081afe4137d444ef85614213b8eb Mon Sep 17 00:00:00 2001 From: Devesh Sharma Date: Thu, 24 Dec 2015 13:14:06 -0500 Subject: [PATCH] RDMA/ocrdma: Dispatch only port event when port state changes Dispatch only port event to IB stack when port state changes. Don't explicitly modify qps to error. Let application listen to port events on async event queue or let QP fail with retry-exceeded completion error.
