Subject: [net-next 08/12] ixgbevf: Do not forward LLDP type frames
Date: Fri, 26 Oct 2012 17:08:34 -0700 [thread overview]
Message-ID: <1351296518-31174-9-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1351296518-31174-1-git-send-email-jeffrey.t.kirsher@intel.com>
From: Greg Rose <gregory.v.rose@intel.com>
The driver should not forward LLDP type frames. Inspect the ether type and
do not send if it is an LLDP ethertype frame.
