Yes, I know.  Unlike Jason and Darren, I don't intend to make a complete
mbuf for bpf.  It is still _hack_ anyway.  Even if these members are also
initialized, the mbuf is still illegal, since it cannot be free..

I just think counting the whole length in bpf_mtap() is not necessary
most cases and make it easier by putting m_pkthdr.len.
But after scanning source tree for dummy mbuf, I would agree that the
change in bpf.c is too expensive than the effectiveness.

I won't modify other files I listed.
