# rate\_control\_send\_low(9)

helper for drivers for management/no-ack frames

## NAME

rate\_control\_send\_low - helper for drivers for management/no-ack frames

## SYNOPSIS

**bool rate\_control\_send\_low(struct ieee80211\_sta \*** *sta***, void \*** *priv\_sta***, struct ieee80211\_tx\_rate\_control \*** *txrc***);**

## ARGUMENTS

*sta*

struct ieee80211\_sta pointer to the target destination. Note that this may be null.

*priv\_sta*

private rate control structure. This may be null.

*txrc*

rate control information we sholud populate for mac80211.

## DESCRIPTION

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.

Rate control algorithms wishing to do more intelligent selection of rate for multicast/broadcast frames may choose to not use this.
