Yes. So one of the.. unfortunately broken things in iwn is the ampdu tx
code doesn't do retransmits. So if amrr picks a rate that fails to transmit
everything, the driver doesn't retransmit them. It frees them.
Now when amrr is enabled the hardware will retry at lower rates until
something succeed

And for reference, here's the paper:

Right near the end there you have 'status 83' which means 'transmit
failed, long retry hit' (the status codes are in if_iwnreg.h
somewhere.) The retry count hit 16, which is the max set for the
frame.
rate=80 (hex) is MCS0. So, you're seeing retransmits and failures at
MCS0, which is a bad sign.

Oh, and you need to print out the tx->rate field using "0x%04x",
rather than %d. The completion value is in hex.

Sure, flip on 'wlandebug +rate' (assuming you compiled with IEEE80211_DEBUG)

Turns out that not enabling MRR causes my Intel Ultimate N WiFi Link
5300 to hang after only a few moments of use.
For now, I've just reverted only those aspects of r257133, enabling
MRR and keeping the rate index lookup, which seems to do something on
my hardware at least (I assume it's not the r
