Add a comment explaining why disc(4) bears the IFF_LOOPBACK flag.
It should be the final follow-up to an old yet unfinished discussion
on whether IFF_LOOPBACK is necessary for disc(4) and why.
Thanks for doing this.
It is also worth noting that blackhole routes in the forwarding table
rely upon there being a lo(4) interface in the system unless fast
forwarding is enabled. This is a 'gotcha' which people may not be aware
of, though I think I may have commented it somewhere...
