value. It is to reduce the packets slightly and enhance network
transmission efficiency.
Please be advised that changing MTU value might result in NIC reboot,
network offline and affect current running operation.

Aggregation mode Description
Load balance
Device has bonded several NICs at the same time and use one IP
address to communicate with the external device. The bonded NICs are
working together to bear the network load.
The load balance mode adds the network throughput data amount and
enhances network flexibility and availability. In this mode, the network
is offline once all NICs break down.
