====================
phylink: API changes

This patch series contains two API changes to PHYLINK which will later be used
by DSA to migrate to PHYLINK. Because these are API changes that impact other
outstanding work (e.g: MVPP2) I would rather get them included sooner to minimize
conflicts.

Thank you!

Changes in v2:

- added missing documentation to mac_link_{up,down} that the interface
  must be configured in mac_config()

- added Russell's, Andrew's and my tags
