Hi James,

        A few comments for you:

Issues found:
    ip6_forward_rt is a global value that is used without locking
    ASSERTS still include the old name apc_inet6_fastfwd
    Stats are updated directly but I don't think we lock those yet.
    Don't define M2MMAX in line, put it outside with a comment.
    If the mbuf is already freed then how can we safely use m->m_pkthdr.rcvif? 
at line 223
    Improve the indenting in the commented case at line 298.  I understand the 
idea, and it's good, but it's a bit confusing to read.
    Remove #if code at 553 which is specific to the APC product.

Later,
George
