Subject: [PATCH] gemini: Fix MAC address assignment for DIR-685
The DIR-685 has the MAC addresses in the RedBoot code just like
DNS-313. Check some magic numbers to determine that the MAC
address is where we want it and extract it from RedBoot.

[replaced ifconfig with ip, ! -z = -n, added string quotes]
