From f7532f73105dc8f05f2970d41b1d71d41d59e8a0 Mon Sep 17 00:00:00 2001 From: "Arnaud Patard (Rtp)" Date: Thu, 26 Jul 2012 12:15:46 +0200 Subject: ARM: Orion: Set eth packet size csum offload limit commit 58569aee5a1a5dcc25c34a0a2ed9a377874e6b05 upstream. The mv643xx ethernet controller limits the packet size for the TX checksum offloading. This patch sets this limits for Kirkwood and Dove which have smaller limits that the default. As a side note, this patch is an updated version of a patch sent some years ago: http://lists.infradead.org/pipermail/linux-arm-kernel/2010-June/017320.html which seems to have been lost.
