Description
The value range is from 1 ms to 5 ms. The default is 1 ms.
When a packet exceeds the fragment threshold, it is divided into
multiple packets. Excessive packet fragments may affect the
network performance, so the fragment threshold should not be set
too big.
It is recommended to set the threshold to an even value. An odd
value is reduced by one to be an even value. The default is 2346.
