    Default - Auto Negotiate
    MTU
    Specify MTU value (Maximum Transmission Unit)
    MTU is the largest physical packet size, in bytes, that a network can transmit. This parameter becomes an issue when networks are interconnected and the networks have different MTU sizes. Any packets larger than the MTU value are divided (fragmented) into smaller packets before being sent.
    Default - 1500
    Input range - 576 to 1500
