Networking: mbuf->m_hdr.mh_data doesn't include DLIL header?

Networking: mbuf->m_hdr.mh_data doesn't include DLIL header?

For certain packets that my iff_input_func is receiving, when I looked
at the entire mbuf structure received in parameter 4, I noticed that
the m_hdr.mh_data field offsets 14 bytes beyond the start of the
ethernet frame.

This is causing my mbuf_dup() cloned mbuf to not contain the 14 bytes
of ethernet header in my NKE.

Looking in the original mbuf received in my iff_input_func, the 14
bytes of ethernet header are in the mbuf body at
mbuf->M_dat.MH.MH_dat.MH_databuf[0..13].

What am I doing wrong? How do I clone the mbuf to include the DLIL header?

Thanks!
