.SH "CONSTANTS"
.PP
IEEE80211_TX_RC_USE_RTS_CTS
.RS 4
Use RTS/CTS exchange for this rate\&.
.RE
.PP
IEEE80211_TX_RC_USE_CTS_PROTECT
.RS 4
CTS\-to\-self protection is required\&. This is set if the current BSS requires ERP protection\&.
.RE
.PP
IEEE80211_TX_RC_USE_SHORT_PREAMBLE
.RS 4
Use short preamble\&.
.RE
.PP
IEEE80211_TX_RC_MCS
.RS 4
HT rate\&.
.RE
.PP
IEEE80211_TX_RC_GREEN_FIELD
.RS 4
Indicates whether this rate should be used in Greenfield mode\&.
.RE
.PP
IEEE80211_TX_RC_40_MHZ_WIDTH
.RS 4
Indicates if the Channel Width should be 40 MHz\&.
.RE
.PP
IEEE80211_TX_RC_DUP_DATA
.RS 4
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\&.
.RE
.PP
IEEE80211_TX_RC_SHORT_GI
.RS 4
Short Guard interval should be used for this rate\&.
.RE
.PP
IEEE80211_TX_RC_VHT_MCS
.RS 4
VHT MCS rate, in this case the idx field is split into a higher 4 bits (Nss) and lower 4 bits (MCS number)
.RE
.PP
IEEE80211_TX_RC_80_MHZ_WIDTH
.RS 4
Indicates 80 MHz transmission
.RE
.PP
IEEE80211_TX_RC_160_MHZ_WIDTH
.RS 4
Indicates 160 MHz transmission (80+80 isn\*(Aqt supported yet)
