[PATCH V2 4/4] net-next: tag_mtk: add nh and proto offsets to the ops struct

From: John Crispin
Date: Fri Jul 21 2017 - 04:59:03 EST


The MT7530 inserts the 4 magic header in between the 802.3 address and
protocol field. The patch defines these header such that the flow_disector
can properly parse the packet and thus allows hashing to function properly.
