In fact, it's commutative, not even as much as line offsets. :)

Well, for one, the PS code is only relevant if we're ourselves operating
in IBSS or AP mode. If we're operating in AP/IBSS mode we'll also
automatically buffer your injected multicast frames for after the DTIM
beacon. I think we should just buffer injected unicast frames as well,
it won't hurt your use case (multicast destination) and makes things
more consistent.

Well, no, that's unrelated, and it's a bug in iwlwifi that it craps out
over that ;)
