[PATCH/RFC,0/2] Add Gigabit Ethernet driver support

Message

Biju Das July 14, 2021, 2:54 p.m. UTC

The DMAC and EMAC blocks of Gigabit Ethernet IP is almost
similar to Ethernet AVB.

The Gigabit Etherner IP consists of Ethernet controller (E-MAC),
Internal TCP/IP Offload Engine (TOE) and Dedicated Direct memory
access controller (DMAC).

With few canges in driver, we can support Gigabit ethernet driver as well.
I have prototyped the driver and tested with renesas-drivers master branch.

Please share your valuable comments.

Thanks.
