  Modified files:
    sys/dev/nge          if_nge.c 
  Log:
  Two optimizations:
  
  1) Bite the bullet, and allow unaligned accesses without buffer copies
     on the i386 platform. According to some tests run by Andrew Gallatin,
     the buffer copy performance hit is greater than the unaligned access
     performance hit (especially with jumbo frames). We still need to copy
     everywhere else.
  
  2) Enable interrupt moderation with a 100us timeout.
