From 182285d0fcaba7b284b4feb71ebad5e7aaea0f4b Mon Sep 17 00:00:00 2001 From: Dennis Dalessandro Date: Fri, 22 Jan 2016 13:01:01 -0800 Subject: [PATCH] IB/rdmavt: Add misc dev register functionality There are a number of minor things that should be set by rdmavt rather than by the drivers. Now that rdmavt has solidified in its design we can go ahead and clean up this stuff.
