This series fixes application of erratum 4.8, adds fix for erratum 5.2, adds support for completely disablign SerDes receiver / transmitter, fixes inband AN for 2500base-x mode by using 1000base-x mode and simply changing frequeny to 3.125 GHz, all this for 88E6393X. The last commit fixes linking when link partner has AN disabled and the device invokes the AN bypass feature. Currently we fail to link in this case.
