From 746b9f0228a1c607b3db67c80da1c2a963321926 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Wed, 16 Jul 2008 20:15:45 -0700 Subject: 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.
