Sorry I missed this the first time we went through this. Putting the &&
ia here causes fragmented packets sent on interfaces without addresses to
not be sent -- which is not really the right plan. I think the if (ia)
belongs around the stats updates, but not around the ifp_output() call.
Testing should include something like "% ping -I 0.0.0.1 -s 2000
224.0.0.1" (where the "1" is the ifindex of an up multicast-capable
interface with no source address and "2000" is larger than its MTU),
and running tcpdump to make sure those packets make it out.
