    I don't know enough to have any serious opinion about virtual IP
    interfaces, but I am very certain that VLANs should appear as
    an interface to external code/user-land, just as eth0 does.

    This hashing helps with VLANs, and since I aim to get VLANs into
    the kernel proper sooner or later, having this piece in there
    makes my patch a little smaller :)

    However, if folks look at the patch and hate it, then it can
    be left out, or changed appropriately.
