Few things I've noticed most of which look like issues against the original
patch and not the MFC but worth mentioning.

1. You've introduced a new tunable kern.maxmbufmem which is autosized but
   doesnt seem to be exposed via a sysctl so it looks like there is no way
   to determine what its actually set to?
2. There's a missmatch between the tuneable kern.ipc.nmbufs in tunable_mbinit
   and the sysctl kern.ipc.nmbuf i.e. no 's'.
3. Should kern.maxmbufmem be kern.ipc.maxmbufmem to sit along side all of
   the other sysctls?
4. style issues:
* @@ -178,11 +202,13 @@
  ...
  if (newnmbjumbo9 > nmbjumbo9&&

Finally out of interest what made us arrive at the various defaults for each
type as it looks like the ratios have changed?
