 *      A-MSDU aggregation.
 *    - The tx frame should not be aggregated (A-MPDU or A-MSDU)
 *    - The tx frame is already encrypted - don't attempt encryption.
 *    - The tx frame is a segment of a TCP jumbo frame.
 *    - This tx frame should not be unmapped and freed by the txrx layer
 *      after transmission, but instead given to a registered tx completion
 *      callback.
 *  More than one of these specification can apply, though typically
 *  only a single specification is applied to a tx frame.
 *  A compound specification can be created, as a bit-OR of these
 *  specifications.
