Add a new QUSGMII mode, standing for "Quad Universal Serial Gigabit Media Independent Interface", a derivative of USGMII which, similarly to QSGMII, allows to multiplex 4 1Gbps links to a Quad-PHY. The main difference with QSGMII is that QUSGMII can include an extension instead of the standard 7bytes ethernet preamble, allowing to convey arbitrary data such as Timestamps.
