  [PATCH V2 4/4] net-next: tag_mtk: add nh and proto offsets to the ops struct John Crispin <john@phrozen.org> - 2017-07-21 11:00 +0200

#1693494 — [PATCH V2 4/4] net-next: tag_mtk: add nh and proto offsets to the ops struct

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.
