From 4200406b8fbbf309f4fffb339bd16c4553ae0c30 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Tue, 11 Mar 2008 18:35:20 -0700 Subject: [PATCH] IPoIB/cm: Set tx_wr.num_sge in connected mode post_send() Commit 7143740d ("IPoIB: Add send gather support") made it possible for tx_wr.num_sge to be != 1 -- this happens if send gather support is enabled. However, the code in the connected mode post_send() function assumes the old invariant, namely that tx_wr.num_sge is always 1. Fix this by explicitly setting tx_wr.num_sge to 1 in the CM post_send().
