+Subject: [PATCH 39/57] 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_disscetor can use to get the correct offsets
+for the protocol field and network header offset.
