From 945eb31337c2a8a09a62dcf5aca260bcde9c2a6c Mon Sep 17 00:00:00 2001 From: Bruce Allan Date: Wed, 28 Oct 2009 18:28:30 +0000 Subject: [PATCH] e1000e: flow control doesn't re-enable When changing flow control (pause) parameters, the flow control thresholds (i.e. when to send XON/XOFF frames) may not be setup correctly on parts with copper media. Call the existing e1000_set_fc_watermarks() function to set these thresholds. Signed-off-by: Bruce Allan Signed-off-by: Jeff Kirsher Signed-off-by: David S.
