NAME
       enum_mac80211_rate_control_flags - per-rate flags set by the Rate Control algorithm.

SYNOPSIS
       enum mac80211_rate_control_flags {
	 IEEE80211_TX_RC_USE_RTS_CTS,
	 IEEE80211_TX_RC_USE_CTS_PROTECT,
	 IEEE80211_TX_RC_USE_SHORT_PREAMBLE,
	 IEEE80211_TX_RC_MCS,
	 IEEE80211_TX_RC_GREEN_FIELD,
	 IEEE80211_TX_RC_40_MHZ_WIDTH,
	 IEEE80211_TX_RC_DUP_DATA,
	 IEEE80211_TX_RC_SHORT_GI,
	 IEEE80211_TX_RC_VHT_MCS,
	 IEEE80211_TX_RC_80_MHZ_WIDTH,
	 IEEE80211_TX_RC_160_MHZ_WIDTH
       };

CONSTANTS
       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.

       IEEE80211_TX_RC_VHT_MCS
	   VHT MCS rate, in this case the idx field is split into a higher 4 bits (Nss) and lower 4 bits (MCS number)

       IEEE80211_TX_RC_80_MHZ_WIDTH
	   Indicates 80 MHz transmission

       IEEE80211_TX_RC_160_MHZ_WIDTH
	   Indicates 160 MHz transmission (80+80 isn't supported yet)

DESCRIPTION
       These flags are set by the Rate control algorithm for each rate during tx, in the flags member of struct ieee80211_tx_rate.
