ath6kl: ignore WMI_TXE_NOTIFY_EVENTID based on fw capability flags
Certain 6004 firmware releases redefine the WMI_TXE_NOTIFY_EVENTID event number and sends the new event frequently. However it doesn't have the tx-err-notify feature and thus this firmware capability flag isn't set on the firmware package. By guarding the processing of this event by the same method we guard the sending of the WMI_SET_TXE_NOTIFY_CMDID command, we can ignore the spurious event that we don't know how to process. Without this change we call cfg80211_cqm_txe_notify() with possibly bad data. Signed-off-by: Steve deRosier <steve.derosier@lairdtech.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
