From 2e96691c31ecf749f48aa94ea837b95dd656f5c2 Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Tue, 28 Feb 2012 18:49:50 +0200 Subject: IB: Use central enum for speed instead of hard-coded values The kernel IB stack uses one enumeration for IB speed, which wasn't explicitly specified in the verbs header file. Add that enum, and use it all over the code. The IB speed/width notation is also used by iWARP and IBoE HW drivers, which use the convention of rate = speed * width to advertise their port link rate.
