Channel Switch Time

we want to implement fast channel switching on ATH10K for IBSS mode. Any 
pointer on firmware modifications that allow to do that fast would be 
appreciated. Currently, we observe a latency of 2.5 sec under traffic. 
Also, 802.11h support for CSA would be nice to have in IBSS mode. How 
can we trigger this? I mean what interface do we have from outside to 
trigger a fast channel switch that then issues a 802.11h CSA so that all 
peers would also switch the channel, ideally in millisecond time?
