Jumbo Mtu
The Jumbo Mtu property allows the adapter to transmit and receive
oversized Ethernet frames that are greater than 1,514 but less than 9,000
bytes in length. Note that this property requires a switch that is able to
process large frames.
By default, the Jumbo Mtu property is set to 1500 bytes.
