734 So in our case,
735 while receiving a packet RX case, if the buffer is full (trypost - it is sys_mbox_trypost)
736 the error will be returned, we can consider that an overflow has happened.
737 So this can be RX overrun.
738
739 But while transmitting a packet TX case, underrun cannot happen because it block on the
740 message Q if it is full (NOT trypost - it is sys_mbox_post). So TX overrun is always 0.
