Subject: [PATCH] forcedeth: mac address fix

This critical patch fixes a mac address issue recently introduced. If 
the device's mac address was in correct order and the flag 
NVREG_TRANSMITPOLL_MAC_ADDR_REV was set, during nv_remove the flag would 
get cleared. During next load, the mac address would get reversed 
because the flag is missing.

As it has been indicated previously, the flag is cleared across a low 
power transition. Therefore, the driver should set the mac address back 
into the reversed order when clearing the flag.

Also, the driver should set back the flag after a low power transition 
to protect against kexec command calling nv_probe a second time.
