[PATCH net-next 00/13] More complete PHYLINK support for mv88e6xxx

[Andrew Lunn <andrew@lunn.ch>]

Previous patches added sufficient PHYLINK support to the mv88e6xxx
that it did not break existing use cases, basically fixed-link phys.

This patchset builds out the support so that SFP modules, up to
2.5Gbps can be supported, on mv88e6390X, on ports 9 and 10. It also
provides a framework which can be extended to support SFPs on ports
2-8 of mv88e6390X, 10Gbps PHYs, and SFP support on the 6352 family.

Russell King did much of the initial work, implementing the validate
and mac_link_state calls. However, there is an important TODO in the
commit message:

needs to call phylink_mac_change() when the port link comes up/goes down.

The remaining patches implement this, by adding more support for the
SERDES interfaces, in particular, interrupt support so we get notified
when the SERDES gains/looses sync.

This has been tested on the ZII devel C, using a Clearfog as peer
device.
