From 598a968011ffc4d624934995fe46d06bd450cdf4 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Wed, 9 Aug 2017 14:41:17 +0200 Subject: [PATCH] net-next: dsa: add flow_dissect callback to struct dsa_device_ops When the flow dissector first sees packets coming in on a DSA devices the 802.3 header wont be located where the code expects it to be as the tag is still present. Adding this new callback allows a DSA device to provide a new function that the flow_dissector can use to get the correct protocol and offset of the network header.
