    Oh right. And Phonet devices don't support scatter/gather, so that I guess
    that would merely delay the problem.

    Also sendmsg() code would need to be reectored to look up the output
    device and then the MTU before allocating the socket buffer. This will only
    work if the default MTU is reduced first :/
