<br>
The alarm timeout is calculated by multiplying wait_msec by<br>
US_PER_MS before passing the value to rte_eal_alarm_set().<br>
<br>
Since wait_msec is a uint32_t, the multiplication may overflow<br>
when performed using 32-bit arithmetic for large timeout values.<br>
<br>
Cast wait_msec to uint64_t to ensure the multiplication is<br>
performed in 64-bit arithmetic.<br>
