hi Johannes,
do you mean the IEEE80211_TX_RC_USE_RTS_CTS flag to set RTS/CTS protection for the packet?
I did not use this based on the below understanding
my understanding for SMPS is that a station system does not need to send an RTS packet before frame transmission for SMPS however an AP system needs to send out an RTS frame.
hence, I defined a new txinfo flag which tells the lower driver (if AP) to send RTS frame if the station for which the packet is scheduled is dynamic SMPS to set the RTS frame for the same.
awaiting your feedback
thanks and regards
Vivek
