.SH "NAME"
rate_control_send_low \- helper for drivers for management/no\-ack frames
.SH "SYNOPSIS"

.BI "bool rate_control_send_low(struct\ ieee80211_sta\ *\ " "sta" ", void\ *\ " "priv_sta" ", struct\ ieee80211_tx_rate_control\ *\ " "txrc" ");"
.SH "ARGUMENTS"
.PP
\fIsta\fR
.RS 4
struct ieee80211_sta
pointer to the target destination\&. Note that this may be null\&.
.RE
.PP
\fIpriv_sta\fR
.RS 4
private rate control structure\&. This may be null\&.

\fItxrc\fR
.RS 4
rate control information we sholud populate for mac80211\&.
.RE
.SH "DESCRIPTION"
.PP
.PP
Rate control algorithms that agree to use the lowest rate to send management frames and NO_ACK data with the respective hw retries should use this in the beginning of their mac80211 get_rate callback\&. If true is returned the rate control can simply return\&. If false is returned we guarantee that sta and sta and priv_sta is not null\&.
.PP
Rate control algorithms wishing to do more intelligent selection of rate for multicast/broadcast frames may choose to not use this\&.
