If pg track is sent during headless synced and being rejected, it will be
resent in avnd_di_resend_pg_start_track(). However, this
avnd_di_resend_pg_start_track() also increases the @snd_msg_id, thus the
pg_start_track msg with msg_id=2 is still in the queue. When it's resent by
avnd_diq_rec_send_buffered_msg(), it will cause msg out of order
Minor bug to be noted here also, msg_id is updated by wrong msg content:
avd_pg_trk_act_evh() {
...
m_AVD_SET_AVND_RCV_ID(cb, node, (n2d_msg->msg_info.**n2d_reg_su**.msg_id));
...
}
