Maxime Chevallier July 28, 2022, 2:52 p.m. UTC 
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.
