Subject: [PATCH] ARC: [axs10x] cap ethernet phy to 100 Mbit/sec
Date: Mon, 7 Dec 2015 14:21:37 +0300 [thread overview]
Message-ID: <1449487297-10093-1-git-send-email-abrodkin@synopsys.com> (raw)
Current ARC SDP boards cannot reliably handle 1Gbit
Ethernet connections due to limitations in hardware.
To make sure networking is stable on the board we're
limiting phy to 100 Mbit.
