Fix connection issue caused by AMPDU frames with abnormal PN patterns (out-of-order packets with correct MPDU sequence numbers but paired with abnormal PN values, which is next PN of previous in-order packet). This is causing packet drops, low throughput and disconnections. It is observed in fields with some specific AP firmwares. Do this workaround for better interoperability since some APs could never receive a proper FW update.
