+ * @details
+ *  Indicate one or more of the following:
+ *    - The tx frame already has a complete 802.11 header.
+ *      Thus, skip 802.3/native-WiFi to 802.11 header encapsulation and
+ *      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.
