Subject: [PATCH net-next v2 0/2] phylink: API changes

Hi all,

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

Provide a pointer to the SFP bus in struct net_device, so that the

Subject: [PATCH net-next v2 1/2] net: phy: phylink: Provide PHY interface to mac_link_{up,down}

In preparation for having DSA transition entirely to PHYLINK, we need to pass a
PHY interface type to the mac_link_{up,down} callbacks because we may have to
make decisions on that (e.g: turn on/off RGMII interfaces etc.). We do not pass
an entire phylink_link_state because not all parameters (pause, duplex etc.) are
defined when the link is down, only link and interface are.

Update mvneta accordingly since it currently implements phylink_mac_ops.
