+ * These flags are used with the @flags member of &ieee80211_tx_control
+ *
+ * @IEEE80211_TXCTL_REQ_TX_STATUS: request TX status callback for this frame.
+ * @IEEE80211_TXCTL_DO_NOT_ENCRYPT: send this frame without encryption;
+ *                                  e.g., for EAPOL frame
+ * @IEEE80211_TXCTL_USE_RTS_CTS: use RTS-CTS before sending frame
+ * @IEEE80211_TXCTL_USE_CTS_PROTECT: use CTS protection for the frame (e.g.,
+ *                                   for combined 802.11g / 802.11b networks)
+ * @IEEE80211_TXCTL_NO_ACK: tell the low level not to wait for an ack
+ * @IEEE80211_TXCTL_RATE_CTRL_PROBE

+ *                                 for destination station
+ * @IEEE80211_TXCTL_REQUEUE:
+ * @IEEE80211_TXCTL_FIRST_FRAGMENT: this is a first fragment of the frame
+ * @IEEE80211_TXCTL_LONG_RETRY_LIMIT: this frame should be send using the
+ *                                    through set_retry_limit configured long
+ *                                    retry value
+ * @IEEE80211_TXCTL_EAPOL_FRAME: internal to mac80211
+ * @IEEE80211_TXCTL_SEND_AFTER_DTIM: send this frame after DTIM beacon
+ * @IEEE80211_TXCTL_AMPDU: this frame should be sent as part of an A-MPDU
+ * @IEEE80211_TXCTL_OFDM_HT: this frame can be sent in HT OFDM rates. number
+ *                           of streams when this flag is on can be extracted
+ *                           from antenna_sel_tx, so if 1 antenna is marked
+ *                           use SISO, 2 antennas marked use MIMO, n antennas
+ *                           marked use MIMO_n.
+ * @IEEE80211_TXCTL_GREEN_FIELD: use green field protection for this frame
+ * @IEEE80211_TXCTL_40_MHZ_WIDTH: send this frame using 40 Mhz channel width
+ * @IEEE80211_TXCTL_DUP_DATA: duplicate data frame on both 20 Mhz channels
