Subject: lisp: Reset vlan tag on send.
X-Git-Tag: v2.1.0~638
X-Git-Url: http://git.cascardo.eti.br/?a=commitdiff_plain;h=df7d2c59fd78907a9f7e3ada021b95a4b9d6470b;p=cascardo%2Fovs.git

lisp: Reset vlan tag on send.

Lisp needs to discards all l2 packet headers but if vlan tx
is hw-acceleraed vlan tag is stored in skb struct. Following
patch resets it.
