For each TCP zero window probe, the icsk_backoff is increased by one and
its max value is tcp_retries2. If tcp_retries2 is greater than 63, the
probe0 timeout shift may exceed its max bits. On x86_64/ARMv8/MIPS, the
shift count would be masked to range 0 to 63. And on ARMv7 the result is
zero. If t
