3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Mirko Lindner <[email protected]> [ 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 Signed-off-by: Mirko Lindner <[email protected]> Acked-by: Stephen Hemminger <[email protected]> Signed-off-by: David S.
