Subject: [PATCH net-next v11 2/6] gre: unset mac header for non-TEB packets received by ipgre device
Date: Wed,  6 Jul 2016 19:59:52 +0200	[thread overview]
Message-ID: <1467827996-32547-3-git-send-email-simon.horman@netronome.com> (raw)
In-Reply-To: <1467827996-32547-1-git-send-email-simon.horman-wFxRvT7yatFl57MIdRCFDg@public.gmane.org>

unset rather than reset mach header for non-TEB packets received by an
ipgre device.  This allows skb_transport_header_was_set to be subsequently
used to differentiate TEB and non-TEB packets recieved on an ipgre device.
