 family of Marvell

Pavana,

please add me to Cc for this.

Does USXGMII mode work? There are some erratas for for 10gb serdes mode.

Also you should split this patch. The code that refactores the
serdes_get_lane methods should be in a separate patch.

I have a device with this switch and also a SFP module which can
operate with USXGMII. I would like to get USXGMII mode to work before
this support is added, if possible. For some reason though I was unable
to get it to work, I will have to look at those erratas.
