please do this via higher-layer mechanisms, for example WWW, SSH or
whatever your slave supports.

The EoE protocol indeed has some communication primitives to set some
IP-layer attributes. My opinion is, that this is a major design lapse. A
network protocol should never include knowledge of a higher-layer
protocol. That's why I didn't implement this. ;-)
