As discussed on the phone, I think this should be okay with wl12xx. We will have to study it a bit further to be sure, but my first impression is that it's should be fine. One small correction from my mistake, wl1251 doesn't have a dummy join, it's the old wl12xx which did (with older firmwares that didn't support roc/croc).
