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

From: Maxime Chevallier <maxime.chevallier@bootlin.com>
Date: 2022-07-28 14:53:21
Also in: linux-devicetree, lkml, netdev
Subsystem: networking drivers, open firmware and flattened device tree bindings, the rest · Maintainers: Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

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.
