Hi,
I'm trying to do a monitor mode vif capture on an AR9280 and
seeing weird behavior with 802.11 ACKs sourced from or destined to my
device. I added the interface like so:
iw dev wlan0 interface add mon0 type monitor flags control fcsfail
(tried multiple flag combos)
ifconfig mon0 promisc
ifconfig mon0 up
When I generate traffic on wlan0 running tcpdump on mon0, I see all
the expected acks for other stations and APs around me, but acks with
my device as the RA show up weirdly delayed or out of order, and I
never see the acks from my device to the AP.
Here's a few seconds of excerpts from the capture illustrating the
issue with my station pinging google (full dump attached):

So the ACK either shows up in my tcpdump very late, or is coming in
out of order with the ping request, and we never see the ACK to the AP
(but we don't see retransmits, so obviously they're coming in and
going out in a timely fashion).
It seems to be 100% reproducible, and doesn't just affect ping. Is
this expected behavior?
I'm on kernel 3.2.2.
Thanks for any insight!
