The MTU that Reticulum adheres to, and will expect other peers to
adhere to. By default, the MTU is 500 bytes. In custom RNS network
adhere to. By default, the MTU is 507 bytes. In custom RNS network
implementations, it is possible to change this value, but doing so will
completely break compatibility with all other RNS networks. An identical
MTU is a prerequisite for peers to communicate in the same network.
