netdrv intel: disable VLAN filtering in promiscous mode
As discussed in this thread:
http://www.mail-archive.com/netdev@vger.kernel.org/msg53976.html
promiscous mode means to disable *all* filters. Currently only unicast
and multicast filtering is disabled. This patch changes all Intel
drivers to also disable VLAN filtering.
