    And I can't thank you enough. I forgot about a few other (rather)
    important file changes this picked up.

    A patchfile for aoe against today's 4.10 source tree
    is at:
             http://www.coraid.com/support/freebsd/aoe.patch

    A few notes:

    The file sys/dev/aoe/aoe4bsd.dd is basic documentation for
    the driver.

    All references to chr major 200 will have to be changed to whatever
    gets assigned, obviously.

    The netisr selected in sys/net/netisr.h was picked at random. Is it
    OK?

    The label typeunknown in sys/net/if_ethersubr.c is added to give
    netgraph a chance to get the packets if AoE is not loaded. Appropriate?

    I dinna know how to fill out the copyright/license comment in the headers,
    but i gave it a shot. Thoughts here would be appreciated.

    TIA to all the curious eyes that skim the driver for glaring flaws.

    Cheers,

    Sam
