[PATCH net-next v5 4/5] net: stmmac: add xPCS functions for device with DWMACv5.1




From: Ong Boon Leong <boon.leong.ong@xxxxxxxxx>

We introduce support for driver that has v5.10 IP and is also using
xPCS as MMD. This can be easily enabled for other product that integrates
xPCS that is not using v5.00 IP.
