[net-next,v2,08/15] net: sparx5: add ops to match data

Commit Message

Daniel Machon Oct. 4, 2024, 1:19 p.m. UTC

Add new struct sparx5_ops, containing functions that needs to be
different as the implementation differs on Sparx5 and lan969x. Initially
we add functions for checking the port type (2g5, 5g, 10g or 25g) based
on the port number. Update the code to use the ops instead of the
platform specific functions.
