I never catched it on unit testing.=20 - second i was using 9xx ucode layout for initvals, so both my 7xx and your 8xx ucode were using invalid values. My just happen to work with no-ht mode, but it was pure luck. Once i fixed it and stopped polluting a beacon bit it the transmission work fine with 10 mbits up and down. I also added some bits to test BT coexistence. Next i'll tackle VHT20/VHT40/VHT80 and then ampdu. I am really excited that the work is finally coming together and i really want to hope that broadcom ac rev1 generation will be the best supported by b43. Alessio
