Subject: [PATCH net-next] net: dsa: felix: provide own phylink MAC operations
Convert felix to provide its own phylink MAC operations, thus
avoiding the shim layer in DSA's port.c.

Back in the thread for the previous posting
https://lore.kernel.org/r/Zh1GvcOTXqb7CpQt@shell.armlinux.org.uk
it was identified that two other sub-drivers also needed an update,
and through that identical code in each was identified. In the
final message of the sub-thread from Vladimir, Vladimir volunteered
to pick this up and I agreed. However, I haven't seen anything yet.
I guess Vladimir's attention is elsewhere, so I've done the minimal
fixup for this driver.
