> Subject: [PATCH] arm/km: change default settings for egiga on mgcoge3un
>
> From: Holger Brunck <holger.bru...@keymile.com>
>
> The reason we need this is that we have the gig port on mgcoge3un
> connected using a back-to-back pair of PHYs. There are no magnetics and
> because of that the port has to be run with a fixd configuration and
> auto-negotiation must be disabled. In the default mode the egiga driver
> uses autoneg to determine port speed - which defaults to 1G (we need
> 100M full duplex).
