From 117e4a311d0004aa3d5a285cb4e57e5bdd3bb644 Mon Sep 17 00:00:00 2001
From: David Andrey <david.andrey@netmodule.com>
Date: Tue, 1 Jul 2014 10:08:44 +0200
Subject: [PATCH 6/7] xilinx_emacps: Set the maximum frame reception size to
1536
To make it possible for the driver to receive packets > 1518,
the mode 1536RXEN is now set in the MAC configuration.
