[OpenWrt-Devel] [PATCH 3/3 v2] gemini: Fix MAC address assignment for DIR-685

[Linus Walleij]

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.

Signed-off-by: Linus Walleij <linus.walleij at linaro.org>

ChangeLog v1->v2:
- Rebase on the other patches
- Use library functions to get partition and hex MAC address
- Use ip to set up mac address
