Thomas, Dave, Adrian, Johannes,

Thanks for comments and encouragement. I bought the TP-Link TL-WA901ND
access point and TP-Link TL-WDN4800 PCIe card. Had no problem getting
them talking to each other with ath9k, and the rate table contains 52
entries, so plenty to start out with.

I've written a follow-up post about it if anybody's interested:

Cheers,

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.

Perhaps. However, existing rate control is *very* tightly coupled to
the driver, and it'd be fairly pointless to disentangle just for the
sake of playing with a rate control algorithm.

Also, the device doesn't support per-frame control nor any kind of
sampling-with-table-fallback, only the rate table that you give to the
device and update.

Btw, mac80211_hwsim with wmediumd doing some medium simulation might
also be something to look at for just extending to VHT.

And come to think of it, there's this new driver Felix et al have been
working on, mt7601u, which also should support proper rate control
APIs.
