Subject: [PATCH net-next] net: dsa: lantiq_gswip: provide own phylink MAC
operations
Convert lantiq_gswip to provide its own phylink MAC operations, thus
avoiding the shim layer in DSA's port.c. For lantiq_gswip, it means
we end up with a common instance of phylink MAC operations that are
shared between the different variants, rather than having duplicated
initialisers in dsa_switch_ops.
