From c04bc3d1f417a8a90eef9ab46523dfd44858b28d Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Fri, 19 Aug 2005 10:33:35 -0700 Subject: [PATCH] [PATCH] IB/mthca: Move WQE structures into their own header Move the definitions of the WQE structures from mthca_qp.c into mthca_wqe.h, so that we'll be able to share them when we add the SRQ code in mthca_srq.c.
