Subject: [79/87] ixgbe: limit VF access to network traffic

2.6.37-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Alexander Duyck <alexander.h.duyck@...el.com>

commit 96cc637235892a102fb829218adac048bd730ab7 upstream.

This change fixes VM pool allocation issues based on MAC address filtering,
as well as limits the scope of VF access to promiscuous mode.
