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!

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.

From: Russell King <rmk+kernel@armlinux.org.uk>

Provide a pointer to the SFP bus in struct net_device, so that the
ethtool module EEPROM methods can access the SFP directly, rather
than needing every user to provide a hook for it.

This probably ought to have your sign-off too as you're passing the

seems to apply to this situation.
