From 907c1a91cc58237c61bd32f16c50d6a461446bf1 Mon Sep 17 00:00:00 2001 From: juhosg Date: Fri, 20 Dec 2013 11:41:23 +0000 Subject: 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.
