Subject: [net-next-2.6 PATCH 1/2] igb: clear VF_PROMISC bits instead of
	setting all other bits

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

This change corrects an issue in which we were setting all flag bits except
for promisc instead of clearing the promisc bits due to the incorrect use
of an |= instead of an &=.
