netxen: fix firmware download
o hold the firmware in memory across suspend, since filesystem may not be up after resuming. o reset the chip after requesting firmware, to minimize downtime for NC-SI. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
