[PATCH 1/4] skge: handle zero address at open

[Stephen Hemminger <shemminger@linux-foundation.org>]

Some motherboards are broken and have no address set. Failing at probe time 
prevents the device from ever being used (like to download a fixed BIOS). Instead
warn on probe and check again when device is brought up. That way the address
can be set.
