Regarding your first question: I believe kern.ipc.nmbclusters controls
what you want. This is a loader.conf tunable so you'll need to reboot.
Network buffer tuning is documented, Section 11.13.2. Please read this
before adjusting the tunable.
It would probably be more effective in the long run to find out why your
mbuf count is so high and determine if said situation is caused by a
problem with the NIC driver, or if there's something going on on your
machine that's causing it.
Regarding your 2nd question: not to my knowledge.
