From 25556ae6b965321c7e7469faa06ddbeae50dac91 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 19 Aug 2015 14:58:43 +0200 Subject: [PATCH] IB: remove xrc_remote_srq_num from struct ib_send_wr The field is only initialized in mlx, but never used. If we want to add proper XRC support it should be done with a new struct ib_xrc_wr. This shrinks the various WR structures by another 4 bytes.
