Ok thanks. I am still trying to familiarize myself with ath10k. A
couple things come to mind:
firstly recently there was a patch that set stations back to
associated during recovery, do you know if the branch you're working
against includes that? I will try to figure that out myself but it's
at least worth considering.
If I remember correctly, the sdio rx involves peeking and checking to
see if the frame/packet continues/has more. In the case of firmware
recovery/reconfig I think current code enables all sorts of debug
pktlog stuff, historically it was maybe used as a hack to check for hw
changes... But I mention it because I think what might be happening in
some cases is fw crash follows a frame that would continue/extend,
which is messing with the content and act_len (maybe?)
I also noticed that with aggregation I wind up getting a
deauth/dissasoc followed by mlme delete sta/peer/key.
I think a retry count could be useful but what do you think of maybe
using an event / timeout?

Ok thanks. I am still trying to familiarize myself with ath10k. A
couple things come to mind:
firstly recently there was a patch that set stations back to
associated during recovery, do you know if the branch you're working
against includes that? I will try to figure that out myself but it's
at least worth considering.
If I remember correctly, the sdio rx involves peeking and checking to
see if the frame/packet continues/has more. In the case of firmware
recovery/reconfig I think current code enables all sorts of debug
pktlog stuff, historically it was maybe used as a hack to check for hw
changes... But I mention it because I think what might be happening in
some cases is fw crash follows a frame that would continue/extend,
which is messing with the content and act_len (maybe?)
I also noticed that with aggregation I wind up getting a
deauth/dissasoc followed by mlme delete sta/peer/key.
I think a retry count could be useful but what do you think of maybe
using an event / timeout?
