A-MSDU reception not working?

I ran iperf on an 802.11ac MacBook Air, through my ath10 AP, and to an
Ubuntu system connected to the AP via Ethernet. The AP was running the
reorder buffer patches, the patch to make A-MSDU bypass the reorder
buffer, and the patch to make amsdu aggregation configurable via
debugfs.

It was notably not running the patch from earlier in this thread to
copy A-MSDU subframes into one skb.
I used a second ath10k AP configured in monitor mode as a Wifi
sniffer. I also gathered pcaps on the MacBook Air and on the Ubuntu
system. Wireshark on the MacBook cannot gather radiotap headers nor
put the interface into monitor mode, so we see only Ethernet frames
and we don't see retransmissions on the Wifi link.
I've attached decodes of the same two packets as captured by the
MacBook, by the sniffer, and by the Ubuntu server.
The MacBook sends two frames, TCP sequence numbers 3065441 and 3066889
(the Wireshark "relative sequence number"). In the Wifi sniffer we see
these being aggregated as two subframes in an A-MSDU frame. The first
time this A-MSDU is sent it is corrupted in the air. We see the TCP
checksum of one of the subframes is wrong, and a few bytes of the
payload replaced with ">%'g9(1$".
The A-MSDU is retransmitted a short time later, and the second time
the TCP checksum of both subframes is correct.
This is all fine so far.
However in the pcap taken from the Ubuntu server, we see TCP sequence
number 3065441 being delivered *twice.* The first time, the TCP
checksum is wrong. The second time the TCP checksum is correct.
To me, it looks like A-MSDU frames with bad FCS are not being
discarded after ieee80211_rx_monitor(). The corrupted frames are being
delivered. Delivering the corrupted frames results in sending more TCP
Dup ACKs for the same sequence number back to the MacBook, and I think
this is what causes the MacBook to decide there is congestion and slow
down.
One note: the wifi sniffer does not show the same corruption to the
same packet as the pcap from the Ubuntu system shows. I think that is
normal: the sniffer won't see precisely the same noise, won't have
precisely the same receive sensitivity, and its antennas are not
pointing in the same direction as the primary AP. If I do this test
again, I'll gather a pcap on the primary AP as well to compare to what
we see on the Ubuntu system.
