3.5.7.10 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Mirko Lindner <mlind...@marvell.com>
commit 74f9f42c1c1650e74fb464f76644c9041f996851 upstream.
The sky2 driver sets the Rx Upper Threshold for Pause Packet generation to a
wrong value which leads to only 2kB of RAM remaining space. This can lead to
Rx overflow errors even with activated flow-control.
Fix: We should increase the value to 8192/8
