sky2: Threshold for Pause Packet is set wrong
[ Upstream commit 74f9f42c1c1650e74fb464f76644c9041f996851 ]
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
