Subject: [net-next-2.6 PATCH 3/3] ixgbe: Only set/clear VFE in
	ixgbe_set_rx_mode

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

There appears to be a stray setting of the VFE bit when registering vlans.
This should not be done as vlan filtering should be enabled any time the
interface is not in promiscous mode
