From: Long Li <longli@xxxxxxxxxxxxx>
Failure to send a packet doesn't mean it's a permanent failure, it can't be
returned to user process. This I/O should be retried or failed based on
server packet response and transport health. This logic is handled by the
upper layer.
Give this decision to upper layer.
