Hi,

Yesterday I explained on OpenWrt forum [0] that there are 2 problems
leading to WARNINGs triggered by brcmf_netdev_wait_pend8021x.

The first one is firmware problem with A-MPDU implementation. I already
reported this in "AMPDU stalls with brcmfmac4366b-pcie.bin triggering
WARNINGs" e-mail thread [1].

Another one (I'm reporting right now) is related to brcmfmac and its
counting of 802.1x packets. The idea is simple:
1) In ndo_start_xmit callback there is check for ETH_P_PAE and code
   increasing 802.1x counter by 1.
2) In brcmf_txfinalize there is check for ETH_P_PAE and code decreasing
   802.1x counter by 1.
This is needed as some operations have to be handled without any 802.1x
packet pending.

Thanks to my debugging code (you can find it at the end) I just noticed
that:
1) Sometimes (very rarely) brcmf_txfinalize doesn't detect 802.1x packet
2) brcmu_pkt_buf_free_skb gets called and skb gets freed
3) Counter remains not-decreased and brcmf_netdev_wait_pend8021x will
   always time out.

I'm not sure why this could be happening. The check for ETH_P_PAE looks
exactly the same in both places. My only idea so far is firmware
corrupting skb data. This fools brcmfmac code and my debugging code was
lucky enough to keep tracing skbs (by their addresses) to notice that.

I'm going to extend my debugging patch by making a copy of eth header
and comparing it with corrupted one. As this bug occurs very rarely it
make take days or weeks to get any update.

I'd love to hear any comment meanwhile.
