+ * These flags are set by the Rate control algorithm for each rate during tx,
+ * in the @flags member of struct ieee80211_tx_rate.
+ *
+ * @IEEE80211_TX_RC_USE_RTS_CTS: Use RTS/CTS exchange for this rate.
+ * @IEEE80211_TX_RC_USE_CTS_PROTECT: CTS-to-self protection is required.
+ * This is set if the current BSS requires ERP protection.
+ * @IEEE80211_TX_RC_USE_SHORT_PREAMBLE: Use short preamble.
+ * @IEEE80211_TX_RC_MCS: HT rate.
+ * @IEEE80211_TX_RC_GREEN_FIELD: Indicates whether this rate should be used in
+ * Greenfield mode.
+ * @IEEE80211_TX_RC_40_MHZ_WIDTH: Indicates if the Channel Width should be 40 MHz.
+ * @IEEE80211_TX_RC_DUP_DATA: The frame should be transmitted on both of the
+ * adjacent 20 MHz channels, if the current channel type is
+ * NL80211_CHAN_HT40MINUS or NL80211_CHAN_HT40PLUS.
+ * @IEEE80211_TX_RC_SHORT_GI: Short Guard interval should be used for this rate.
