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.
