Subject: [METH]: Fix MAC address handling.
X-Git-Tag: firefly_0821_release~23856^2~28
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=edba2a1fefc6296bc527754dee1c72a625bb675a;p=firefly-linux-kernel-4.4.55.git

[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.
