Hi,

I'd appreciate any reviews of this patch:

  ftp://ftp.whistle.com/pub/archie/misc/NGETHER.patch

What this does is:

  - Change the ng_ether(4) netgraph node type to get rid of the
    "divert" and "orphans" hooks, replacing them with these hooks:

      "lower" - connection to the raw device
      "upper" - connection to the upper protocol layers

    This should allow much more interesting Ethernet operations 
    using netgraph, especially things that filter, etc. For example,
    bridging can all be done with a netgraph node.

  - Moves all the netgraph-specific functionality out of net/if_ethersubr.c
    and into a new file netgraph/ng_ether.c

  - Allows a KLD for ng_ether.ko so your kernel doesn't have to
    be compiled with options NETGRAPH to use it. When loaded, all
    ethernet interfaces become netgraph nodes as well.. including
    PCCARDS inserted later.

Note: ppp(8) will have to be modified slightly before this gets commited;
haven't done this yet but it should be trivial.

Thanks,
-Archie
