Subject: [RFC net-next 0/6] ethernet: add eth_hw_addr_set_port()

While doing the last polishing of the drivers/ethernet
changes I realized we have a handful of drivers offsetting
some base MAC addr by an id. So I decided to add a helper
for it. The helper takes care of wrapping which is probably
not 100% necessary but seems like a good idea. And it saves
driver side LoC (the diffstat is actually negative if we
compare against the changes I'd have to make if I was to
convert all these drivers to not operate directly on
netdev->dev_addr).

Sending as RFC, because feedback welcome.. and it may
be weekend for Ido.

Jakub Kicinski (6):
  ethernet: add a helper for assigning port addresses
  ethernet: ocelot: use eth_hw_addr_set_port()
  ethernet: prestera: use eth_hw_addr_set_port()
  ethernet: fec: use eth_hw_addr_set_port()
  ethernet: mlxsw: use eth_hw_addr_set_port()
  ethernet: sparx5: use eth_hw_addr_set_port()
