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.
