From 51df60f5a428c249cd458451e0b56269417f3cda Mon Sep 17 00:00:00 2001
From: "David S. Miller" <davem@davemloft.net>
Date: Wed, 8 Apr 2015 16:30:01 -0400
Subject: [PATCH] sfc: Revert SRIOV changes.

This reverts commits:

d92916f71a57582ce7276547510cedb2c10b6bd6 ("sfc: Own header for nic-specific sriov functions,")
25672dba9535b804331145379c79f835ba2205c5 ("sfc: Enable VF's via a write to the sysfs file
 sriov_numvfs")

As they break the build with SRIOV disabled and there is no
easy way to fix it the way things are arranged.
