I use Ingo's tip tree and this build error not occur in my test, I also find
ETH_P_IEEE802154 is added by Sergey Lapin's patch, it's merged recently, can
be found here:
	http://marc.info/?l=git-commits-head&m=124515655608598&w=2

Could you check ETH_P_IEEE802154 is defined in include/linux/if_ether.h and
your code is the latest?

Thanks,
