commit 82d1a8ebf19a1b9841ee44ce7b2448114be3e772 Author: Patrick McHardy kaber@trash.net Date: Wed Apr 24 17:42:56 2013 +0200
net: vlan: add protocol argument to packet tagging functions
Add a protocol argument to the VLAN packet tagging functions. In case of HW tagging, we need that protocol available in the ndo_start_xmit functions, so it is stored in a new field in the skb. The new field fits into a hole (on 64 bit) and doesn't increase the sks's size.
