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.
