Actually, I think the field kinda already covers that.

If you have sampling position 0, then it ought to be of *that* MPDU, so
probably not present in any subframes but the first, unless you can
sample a different timestamp for each.

If you have sampling position 1 (PLCP start) then obviously that's at
the A-MPDU level and it doesn't matter if it's present in all or the
first only, in some ways. (Note that we found that Broadcom generates
an invalid A-MPDU reference field...)

Sampling position 2 - end of frame - I'll clarify to be "end of PPDU",
I think that's what ath* devices create.
