todd 4dbc6a7738 o from the qemu mailing list, prompted by brad@, improve userland
networking througput since otherwise the emulated NICs didn't
  have a way of indicating the receive queue is full and would
  drop packets.
o bump PKGNAME
o inttypes.h made irrelevent a few chunks of patches, so use it instead
