From 6e87d1500713767866db0668bbcec75719576f3c Mon Sep 17 00:00:00 2001 From: Ralph Campbell Date: Wed, 7 May 2008 10:57:14 -0700 Subject: [PATCH] IB/ipath: Only increment SSN if WQE is put on send queue If a send work request has immediate errors and is not put on the send queue, we shouldn't update any of the QP state. The increment of the SSN wasn't obeying this.
