==== Port wscale branch against current gPXE master ====
Recent TCP updates is a lot different from previous base of wscale branch.

==== Window size difference ====
  * Test target image on BKO: http://130.239.17.17/bko/live/fedora/f13-alpha/i686/initrd0.img
  * Image size: 43,355,267 bytes
  * Linux wget speed: 1MByte/s (My Internet link speed is 10Mbit/s, it's about the full spped.)
  * Tested it with emulated rtl8139 of KVM, and Native on rtl8139 hardware.
