Hi Alexander,

In the case of a beacon, 7.3.1.2 Beacon frame MHR field indicate:

	When the Frame Version field is 0b00–0b01:
		— The Destination Addressing mode field shall be set to
		indicated that the Destination Address and Destination
		PAN ID fields are not present.

So I think the NO_ADDRESSING choice here is legit. The destination
field however is useful in the Enhanced beacon frame case, but that's
not yet supported.

Thanks,
Miquèl
