File libmlx4-Remove_compatibility_with_libibverbs-1.1.7.patch of Package libmlx4-rdmav2
From bcc5d064268073cb996bdbac1ae36728db3b2c96 Mon Sep 17 00:00:00 2001 From: Roland Dreier <roland@purestorage.com> Date: Wed, 1 Jan 2014 00:23:43 -0800 Subject: [PATCH 2/4] Remove compatibility with libibverbs < 1.1.7 Since the changes to add verbs extensions / XRC support will break compatibility with libibverbs < 1.1.8, take this chance to strip out all the backwards compatibility code that won't make any sense once we do that.
