Feel free to change these values to test if this has any impact. As far as I am aware, these number are the result of an educated guess based on how minstrel works.

I don't think unicast ELP were supposed to be affected by changing the elp_interval. Smells like a bug to me. Antonio ? Cheers, Marek
