From 74f9f42c1c1650e74fb464f76644c9041f996851 Mon Sep 17 00:00:00 2001 From: Mirko Lindner Date: Tue, 26 Mar 2013 06:38:42 +0000 Subject: [PATCH] sky2: Threshold for Pause Packet is set wrong 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 Signed-off-by: Mirko Lindner Acked-by: Stephen Hemminger Signed-off-by: David S.
