This patch fixes a problem plaguing Dell notebooks with
built-in b44 ethernet:  The driver refuses to transmit packets
of any kind until after the first 5-second tx_timeout occurs.
This bug causes DHCP negotiation to fail (timeout) during
installation of Ubuntu Linux.

One-liner fix.  Please review (and apply if you like it).
