set it  via /boot/loader.conf:
net.isr.bindthreads="1"                         # Bind netisr threads to
CPU cores
net.isr.maxthreads="8"                          # Set number of threads to
number of CPU cores
net.isr.numthreads="8"                          #    ""

The net.isr.dispatch is automatically set to direct on our systems.  Not
sure if that's the default or not.  We used to set that via
/boot/loader.conf as well, but it was removed in the upgrade to 9-STABLE
something as it no longer did anything.
