        * kernel_socket.c (kernel_read): Look up interfaces by index
        first, so that state changes which do not include a sockaddr_dl
        now work.  Add many sanity checks.  In
        particular, do not assume that a sockaddr_dl follows a message
        without checking the ifm_addrs flags, and do not trust the length
        in a sockaddr_dl.  Add/clarify many comments.
