    2728= Using Jumbo Ethernet Frames =
    2829The WARP hardware design supports Ethernet packets up to 9000 bytes. Any Ethernet packet larger than 1500 bytes is considered a "jumbo frame" and support for these jumbo frames among consumer NICs and switches is limited. To see if your hardware supports jumbo frames, increase the MTU setting on your computer to the maximum allowed setting. Then, two tests can determine the maximum usable payload: (a) a ping test, and (b) a WARPLab test.

    3031== Ping Max Payload Test ==
    3132Once the MTU on your machine is raised to its maximum, you can use pings from your computer to determine whether your switch and NIC can actually send and receive jumbo frames. Make sure you have a board configured with the WARPLab bitstream and a DIP switch of '0' (making its IP address 10.0.0.1).
