From b1190d3e0d548615ee7c38c10b5fc376a76b7afd Mon Sep 17 00:00:00 2001 From: Faisal Latif Date: Wed, 9 Dec 2009 15:54:32 -0800 Subject: RDMA/nes: FIN during MPA startup causes timeout A FIN that is received during an MPA start up sequence causes a timeout in iwcm.c. The connection has not been completely closed so the iwcm code is waiting for resources to be cleaned up. This closes the connection so everything cleans up correctly.
