And, as I realized, and as Johannes noted, the radiotap A-MPDU Status field
includes the delimiter CRC, and the other data in the delimiter is redundant
(the reserved field is reserved, the length is the length of the MPDU, and the
"unique data" is the ASCII code for the letter "N"), so there's no reason to
include the MPDU delimiter in the capture.
