This is a zero-copy networking implementation of Ethernet driver. Limitations: - one shot PHY setup, no support for PHY disconnect/reconnect - no support for devices with DCache enabled due to missing non-cacheable RAM regions in Zephyr. Tested on Atmel SMART SAM E70 Xplained board Origin: Original Jira: ZEP-1492 Change-Id: Ib944f91193efbd12c1142b0bcf1f635388bf1b87 Signed-off-by: Piotr Mienkowski <piotr.mienkowski@gmail.com>
