Subject: [RFC PATCH] dt-binding: net: sfp binding documentation

Add device-tree binding documentation SFP transceivers. Support for SFP
transceivers has been recently introduced (drivers/net/phy/sfp.c).

Signed-off-by: Baruch Siach <baruch@...s.co.il>
---

The SFP driver is on net-next.

Not sure about the rate-select-gpio property name. The SFP+ standard
(not supported yet) uses two signals, RS0 and RS1. RS0 is compatible
with the SFP rate select signal, while RS1 controls the Tx rate.
