One more thing, sorry.  This feature is typically implemented today in
user-space on a per-interface basis.  The example I'm thinking of is
Quagga's "link-detect" directive which goes on an interface.  Should
this be a bool on each interface in systcl?  That would let user not
enable on selected interfaces.
