- 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.
