Release 4.11 net/8021q/vlan_dev.c
/* -*- linux-c -*-
* INET 802.1Q VLAN
* Ethernet-type device handling.
*
* Authors: Ben Greear <greearb@candelatech.com>
* Please send support related email to: netdev@vger.kernel.org
* VLAN Home Page: http://www.candelatech.com/~greear/vlan.html
*
* Fixes: Mar 22 2001: Martin Bokaemper <mbokaemper@unispherenetworks.com>
* - reset skb->pkt_type on incoming packets when MAC was changed
* - see that changed MAC is saddr for outgoing packets
* Oct 20, 2001: Ard van Breeman:
* - Fix MC-list, finally.
* - Flush MC-list on VLAN destroy.
