Subject: [PATCH] forcedeth boot delay fix

From: Ayaz Abdulla <[email-masked]>
Date: Sun, 18 Nov 2007 14:13:41 -0500

This patch fixes 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.
