The MTU is decided by the operating system's network stack.  As Emile
said, RabbitMQ has no way to observe or control the MTU.

I'm not sure why you would be concerned about the MTU.  Perhaps you
could tell us what you are trying to achieve, in order for us to give
useful advice?  Otherwise, MTU settings are probably something to
discuss on an operating system specific forum.
