Subject: [PATCH] METH: fix MAC address handling

meth didn't set a valid mac address during probing, but later during
open. Newer kernel refuse to open device with 00:00:00:00:00:00 as
mac address -> dead ethernet. This patch sets the mac address in
the probe function and uses only the mac address from the netdevice
struct when setting up the hardware.
