  Modified files:
    sys/pci              if_pn.c if_pnreg.h if_xl.c if_xlreg.h 
    sys/alpha/conf       GENERIC 
  Log:
  Make the xl and pn drivers work on FreeBSD/alpha and add them to
  sys/alpha/conf/GENERIC.
  
  Note: the PNIC ignores the lower few bits of the RX buffer DMA address,
  which means we have to add yet another kludge to make it happy. Since
  we can't offset the packet data, we copy the first few bytes of the
  received data into a separate mbuf with proper alignment. This puts
  the IP header where it needs to be to prevent unaligned accesses.
  
  Also modified the PNIC driver to use a non-interrupt driven TX
  strategy. This improves performance somewhat on x86/SMP systems where
  interrupt delivery doesn't seem to be as fast with an SMP kernel as
  with a UP kernel.
