I tested this patch.

  # kldload pf
  # kldunload pf
  kldunload: can't unload file: Device busy

The fact that the pf module cannot be unloaded was one of the
reasons that @glebius used to back out the entire changeset last time
I committed your pf changes.  Can you fix this?

I also saw this in dmesg:
