Ok. Please file a PR with all these details, including that ampdutx
broke things.

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,
