be2net: Bug fix to avoid soft lockup in loopback test.
This change ensures that loopback test command gives up after 4 seconds when the hardware is not responsive. This could happen if the ports are connected properly in loopback mode. Signed-off-by: Sarveshwar Bandi <sarveshwarb@serverengines.com> Signed-off-by: David S. Miller <davem@davemloft.net>
