    - Delays or eliminates some IRQs  It'll mostly affect control
       or iso transfers, which typically have multiple TDs per URB,
       by making only the last TD generate an IRQ.
    
    - Shortens some of the submit path that needs to run with
       IRQs disabled ... no need to use the dma_to_td hashtable.
       (Of course that path is still pretty long...)
    
    - Gets rid of case where the ED state was confused ... now
       there's only one such state, not two.
