The reason I didn't for ICMPMsgStats is the size. The RFC requires
in & out counters for all types, whether or not they are known by the OS,
so that's 512 stats.
Because the MIB variables in the existing infrastructure are not
dynamically
allocated, that's:
512 * numInterfaces * numCPUs * 2protos
That seems like a lot of mostly-zero memory. Changing them to be run-time
allocated (and re-allocated when new types are seen) is another
alternative,
but more significant changes.

So maybe it's not so bad -- I'll roll another per-interface version
to see.
