Sorry, I really double check and compile test.

Sorry, but this patch is wrong. The variable i is used in line 513
inside the CMD() macro. The compiler clearly tells this when running
with your patch:
net/ieee802154/nl802154.c: In function ‘nl802154_send_wpan_phy’:
net/ieee802154/nl802154.c:513:4: error: ‘i’ undeclared (first use in
this function)
I would appreciate if patches sent out would at least be compile tested.
