Franco Fichtner 26c5cf989f dummynet: passin after dispatch 
Based on a patch originally found in m0n0wall, expanded
to IPv6 and aligned with FreeBSD's IP input path.

The limit may not be correctly accounted for on the WAN
interface due to dummynet counting the packet again even
though it was already processed.

The problem here is that there's no proper way to reinject
the packet at the point where it was previously removed
from so we make the assumption that ip input was already
done (including pfil) and more or less directly move to
packet output processing.

While here move the passin label up to take the extra check
but avoiding a second label.  Also remove the spurious tag
read for forward check since we don't use it and we should
really trust the mbuf flag.
