From f2cd3399f729332fa3359266d57e441c9888cffe Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Fri, 20 Dec 2013 11:41:23 +0000 Subject: [PATCH] ar71xx: allow to use large ethernet frames on AR934x SoCs The hardware supports large ethernet frames. Override the maximum frame length and packet lenght mask in the platform data to allow to use large MTU on the ethernet interfaces. Limit the feature to AR934x SoCs for now. It should work on some other SoCs as well, but those has not been tested yet.
