This seems changeable by passing a boolean true argument to
RegisterProtocolHandler () in Ipv4L3Protocol::AddInterface().  This
variant could be exposed as an Ipv4 attribute in the future, if needed.

Would this work for you?

I agree that this SendsFrom() checking should be removed from this
function.
