  - Don't claim 7422 MTU size is support by various 8111/8169 chips (PCI devices);
    6144 MTU size works reliably.
      Set MTU above 6144 (6 * 1024) on these chips and do following test:
      netperf -H host -l 30 -t UDP_STREAM -- -m (mtu-28)
      All kinds of wiredness will pop up on the test box.
  - Set max supported MTU to 9216 for 8168D.
    Obtained-from: Realtek r8168-8.008.00
  - Set max supported MTU to 6144 for non-8168D GigE chips.
  - Cleanup jumbo frame/MTU size related macros.
  # As usual, 8169(with 88E1000 PHY) does not seem to work well with any jumbo
  # frame size
