While the vendor SDK stuffs all this into their Ethernet driver, I've tried to seperate things into a PHY driver, a PCS driver as well as changes to the existing Ethernet and LynxI PCS driver. +----------------+ +--------------+ | USXGMII PCS | +------------------+ | Ethernet MAC +--+-------------+ +---+ PEXTP SerDes PHY | +--------------+ | SGMII PCS | | +------------------+ +-------------+--+ Alltogether this allows using GMAC2 and GMAC3 with all possible interface modes, including in-band-status if needed.
