Please file a PR with all these details, including that ampdutx broke things. >> Do you have a freebsd 11n Sta that can be used in mpnitor mode? > > Unfortunately, no.

I'd like to get the ampdu tx issues fixed more than anything else. I bet that it's something to do with the starting point of the aggregation session (ie, what sequence number it begins at.) I'll have to do some further digging, but I don't currently have anything with that Broadcom NIC in it. Let me see if I have a broadcom 802.11n NIC in here and if so, I'll whack it into a Linux laptop and do some basic testing. Thanks, Adrian
