By the way, is the "m->m_data += 2;" still a neccesary evil to
apease NFS?  I have always seen it in drivers but I never understood
why it was there or if I really needed to follow it.  

from if_ed.c: 2727-2732

        /*
         * The +2 is to longword align the start of the real packet.
         * This is important for NFS.
         */
        m->m_data += 2;
        eh = mtod(m, struct ether_header *);
