At least the PCI device generate one tx status report per MPDU, so each subframe
has its own tx status. Only the PACKET_ID field is always taken from
the first frame
of an AMPDU.
And the TX_STA_INFO register can only hold 16 tx status reports and (at least on
PCI devices) it can overflow, thus dropping the status of some frames ...
