I'm using recent brcmfmac and brcmfmac43602-pcie.ap.bin that currently

In OpenWrt we have hostapd with a feature of banning STAs. It works in
a quite simple way. Whenever hostapd gets NL80211_CMD_NEW_STATION for
STA that is banned it sends NL80211_CMD_DEL_STATION.

The problem is that in such case BCM43602 firmware happens to randomly
send more than 1 BRCMF_E_DEAUTH event. It seems it can send random
amount between 1 and 3. Looks a bit like some kind of race. It's
nothing really critical, just makes hostapd log a bit confusing.

Could someone at Broadcom look at firmware source to see if you can
fix this, please?

Hey, I didn't get any reply on this for a year. I just saw similar
problem with
BCM4366. Below you will find a nice log with my extra comments.

Could take a look at this issue this time, please?

Can try.

Thank you and sorry for my late reply! I'm back home now ready to provide any
extra details.


I think it may be another problem related to the A-MPDU thing (bug?) I
reported
in "AMPDU stalls with brcmfmac4366b-pcie.bin triggering WARNINGs" e-mail
thread.

So what firmware version do you have? A colleague pointed me to firmware
fix that may be related so I want to know the target string to build.
Firmware version is in the bin file:

$ hexdump -C fw.bin | tail -40

Well, I am pretty sure I was using the one released by Broadcom. Also my only
device with 4366b1 is DIR-885L. Once I was looking for 4366c0 firmware as
described in the kernel's bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=135321
but I don't think I replaced them or anything.

Anyway, I repeated my tests paying attention to the firmware file. I'm pretty
sure it's the same one you can find in:
https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/brcm/brcmfmac4366b-pcie.bin

And there is a log using that very firmware I verified above.
