I have no real preference on whether it is passed in from the outside vs not. 
But, there's another thing to consider here.  Today the call to l_foo_set_rtnl 
is used determine whether the dhcp/icmp/dhcp6 object should set everything up 
directly vs letting the outside layer do this.  With l_netconfig I don't think 
this is a problem per se, but you should consider the other classes when you 
design this.

We can start by trying to come up with a nice ell API for obtaining the 
singleton rtnl object and go from there.
