Yes, only with iw and nothing fancy, I also have had it running on some 
boards for some weeks as is and with rfc version for more than a year at

I guess I can take the tip of wireless-testing but can you give your
HEAD though ?

Have you reproduced it with other testcases (maybe more regular so that
I can get my hands on it faster) ?
Is it also happening when VHT support is not advertized by upper layers
