    if_de: Sync with current FreeBSD version (r271849). Now works with >4G ram.
    
    * if_de now uses the bus_dma api for DMA memory handling. This makes the
      driver work on systems with more than 4G of ram.
    
    * Remove currently unused code for the TULIP_DO_GPR_SENSE option.
    
    * Keeps most original modifications relative to the code from FreeBSD.
