Subject: forcedeth boot delay fix
From: Ayaz Abdulla <aabdulla@xxxxxxxxxx>
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.
