DPDK does not have a clear concept of MTU

It alters the length when allocating memory

In the case of the MAX profile, increasing the MTU size results in a reduction in the transmission cycle

This may lead to an unintended transmission cycle

Please check the logs when changing the settings\

The final transmission size is determined by the maximum receive size on the target side and the maximum size of the Ethernet hardware.

Therefore, setting a value larger than necessary serves no purpose other than to increase memory consumption.
