net: pcs: xpcs: add CL37 1000BASE-X AN support
For CL37 1000BASE-X AN, DW xPCS does not support C22 method but offers C45 vendor-specific MII MMD for programming. We also add the ability to disable Autoneg (through ethtool for certain network switch that supports 1000BASE-X (1000Mbps and Full-Duplex) but not Autoneg capability. v4: Fixes to comment from Russell King. Thanks! https://patchwork.kernel.org/comment/24894239/ Make xpcs_modify_changed() as private, change to use mdiodev_modify_changed() for cleaner code. v3: Fixes to issues spotted by Russell King. Thanks! https://patchwork.kernel.org/comment/24890210/ Use phylink_mii_c22_pcs_decode_state(), remove unnecessary interrupt clearing and skip speed & duplex setting if AN is enabled. v2: Fixes to issues spotted by Russell King in v1. Thanks! https://patchwork.kernel.org/comment/24826650/ Use phylink_mii_c22_pcs_encode_advertisement() and implement C45 MII ADV handling since IP only support C45 access.
