Date: Mon, 27 Jan 2014 07:59:25 +0400 From: Max Filippov <jcmvbkbc@...il.com> To: linux-xtensa@...ux-xtensa.org, netdev@...r.kernel.org, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Chris Zankel <chris@...kel.net>, Marc Gauthier <marc@...ence.com>, "David S. Miller" <davem@...emloft.net>, Grant Likely <grant.likely@...aro.org>, Rob Herring <rob.herring@...xeda.com>, Max Filippov <jcmvbkbc@...il.com> Subject: [PATCH 1/3] net: ethoc: don't advertise gigabit speed on attached PHY OpenCores 10/100 Mbps MAC does not support speeds above 100 Mbps, but does not disable advertisement when PHY supports them. This results in non-functioning network when the MAC is connected to a gigabit PHY connected to a gigabit switch. The fix is to disable gigabit speed advertisement on attached PHY unconditionally.
