From aa13bd6ef4ddd81080f972220fae30eb28f65b17 Mon Sep 17 00:00:00 2001 From: Ron Mercer Date: Wed, 17 Feb 2010 06:41:23 +0000 Subject: [PATCH] qlge: Fix occasional loopback test failure. On some servers we see the cleaning of the RX queue finish before all the loopback packets are sent out. This delay allows the queues to settle before checking for successful completion. Also, delay completion so link has time to come back up. Signed-off-by: Ron Mercer Signed-off-by: David S.
