From da12eb42aa3f4c7a38ca3dcb01ba4db11a804ad1 Mon Sep 17 00:00:00 2001 From: Ayaz Abdulla Date: Wed, 21 Nov 2007 15:02:58 -0800 Subject: [PATCH] forcedeth boot delay fix patch 9e555930bd873d238f5f7b9d76d3bf31e6e3ce93 in mainline. Fix a long boot delay in the forcedeth driver. During initialization, the timeout for the handshake between mgmt unit and driver can be very long. The patch reduces the timeout by eliminating a extra loop around the timeout logic.
