Subject: [PATCH net-next 01/18] dt-bindings: net: renesas,etheravb: Document Gigabit Ethernet IP

Document Gigabit Ethernet IP found on RZ/G2L SoC.

Gigabit Ethernet Interface includes Ethernet controller (E-MAC),
Internal TCP/IP Offload Engine (TOE) and Dedicated Direct memory
access controller (DMAC) for transferring transmitted Ethernet
frames to and received Ethernet frames from respective storage
areas in the URAM at high speed.
