Subject: net: phy: add USXGMII link partner ability constants
Git-commit: c4471ad9a50d5548e66ae4511acfb1dc23a48744
Patch-mainline: v5.9-rc1
References: jsc#SLE-12251
The constants are taken from the USXGMII Singleport Copper Interface
specification. The naming are based on the SGMII ones, but with an MDIO_
prefix.
