Unfortunately your setups don't gain benefits from NET_MPSAFE in
netbsd-8/-current.
Layer 4 and sockets are still in KERNEL_LOCK and/or softnet_lock and bnx
isn't MP-safe yet.

The best setups benefited from NET_MPSAFE is a router with Intel NICs
(wm or ixg)
and npf.

You can check doc/TODO.smpnet to know what are MP-safe and what are not.
