Hi Ron,

It seems that after commit b4b5e1f49e9982a1ea0b3408e0df6adee49dad54

    mac80211: tear down of block ack sessions
    
    This patch adds a clean tear down for all block ack sessions if interface
    goes down or if a deauthentication is done.

we have a slew of messages saying

[18131.640793] Stop a BA session requested for 00:1a:2a:2c:a2:c5 tid 13
[18131.640798] Try to stop Tx aggregation on non active TID

just like we had for the RX case before.

Please decide once and for all decide whether it is valid to call those
functions, now especially ieee80211_stop_tx_ba_session() when no session
was created.

As indicated by this message rate control algorithms shouldn't call this
function when no TX BA session is present. Therefore the stack itself
shouldn't do so either. The same holds for RX BA sessions.

Please make sure the stack itself always uses the functions only as
specified by their API. Feel free to change the API to allow calling a
function without as session in progress, but in that case please don't
print out anything at all.

Thanks,
johannes
