ÊÅ> that having direct_force = 0 and direct = 0 it is DISPATCH_DEFFERED

setting this to
net.isr.direct=1
net.isr.direct_force=1
in /boot/loader.conf
has no effect
# sysctl net.isr
net.isr.numthreads: 4
net.isr.maxprot: 16
net.isr.defaultqlimit: 256
net.isr.maxqlimit: 10240
net.isr.bindthreads: 0
net.isr.maxthreads: 4
net.isr.direct: 0
net.isr.direct_force: 0
net.isr.dispatch: direct
It seems has been broken in r222249
