hiya, there's a tplink RTL81xx 11ac NIC that's growing linux and freebsd support. I believe it's software rate controllable. The intel 7260 and later parts also allow user controllable rate control and provide transmit completion feedback, but I don't know whether it's enough for your needs.

2016-10-23 Thread Björn Smedman
Hi all, I've been thinking about rate control a bit lately. I've written up some of my thoughts in a blog post (http://www.openias.org/bayesian-wifi-rate-control), but very briefly put I'd like to build a rate control algorithm based on Bayesian statistical inference, possibly by modeling the
