Hi,
9k jumbos is ubiquitous now. I believe we use 9k jumbos for last four
years or more.
You've got unworkable system after upgrade from 8.1 to 8.2 and
documentation doesn't help here. It isn't a good way is made driver (or
system) which doesn't work with jumbo by default.
My point is if you're using machine with 8 CPUs than
maxusers/clusters/9k mbufs should have been increased by system, because
on this machine minimum 2Gb memory is available.

Our validation group has a default postinstall process, every
installed system gets those changes,
and these mbuf pool sizes are in that set of changes. While I'm not
opposed to system default settings
changing its usually necessary to have local sys changes anyway, after
all you don't get 9K jumbos
without manually specifying them as well :)
Regards,
Jack

Hi,
New igb driver (and I think em too) is required too much 9k mbufs
when it's been configured with mtu = 9000. On machine with 8 CPUs,
driver is required 8192 9k mbufs, but by default there is only
6400 and network won't start. In previous versions for big mtu it
was used 4k mbufs, by default there is 12800 and all worked fine.
Maybe it's time to think about increasing default
kern.maxusers/kern.ipc.nmbclusters? or use mp_ncpus for
calculation these values? or just increase amount of
mbuf_cluster/mbuf_jumbo_page/mbuf_jumbo_9k from that driver...
I just want igb to work out-of-the-box.
