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.
