Help¶

Sets the Maximum Transmission Unit (MTU) for the Ethernet over RTT network interface. Ethernet default is 1500 and using different value may cause unpredictable behavior. Change this value only if you really known what you are doing. IPv4 requires at least 68 and IPv6 requires at least 1280.

Direct dependencies¶
