If there is an error on the data that GMPC received, GMPC requests restarting SYNC
SEQUENCE via transmitting REQUEST_RESTART_SYNC frame to the Host system.
Since the Host system receives REQUEST_RESTART_SYNC frame from GMPC, it restarts
SYNC SEQUENCE as requested.
If there is an error on the data that the Host system received, the Host system restarts
SYNC SEQUENCE via transmitting SYNC_PRECI_SYNC frame to GMPC.
