[PATCH net-next 2/4] dt-bindings: net: ethernet-controller: add QUSGMII mode

From: Maxime Chevallier
Date: Thu Jul 28 2022 - 10:53:21 EST


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.
