From fc1f9ea51de726b3b8003539788d918814c9deff Mon Sep 17 00:00:00 2001 From: Ron Mercer Date: Tue, 3 Mar 2009 12:10:37 +0000 Subject: qlge: Add support for lost firmware events. When the firmware is issuing events to the driver the events must be removed from the queue. If the queue overflows, the firmware will build and special event that captures those that are lost.
