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)

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