    ath10k: workaround corrupted htt rx events · 63838640

    qca6174 WLAN.RM.2.0-00073 firmware uses full rx
    reordering offload and delivers Rx via a new HTT
    event. The event however is incorrectly generated
    in firmware and becomes overly long (with trailing
    garbage). This was hitting defined CE buffer limit
    that was programmed to the device and caused
    device to crash upon busier Rx traffic.
    
    Increasing the CE buffer limit for HTT Rx pipe to
    2KBytes seems to be enough to workaround this
    problem.
