System Config:
{{{
Ubuntu Version: Ubuntu 9.04
Netfpga Version: 2.1.0
Openflow Version: 1.0.0
flowvisor Version: Alpha version 0.4
}}}

Note: Bitfiles come from some other package and must be made to agree with the versions of cpci tools and nf2 kernel module

Basic Usage:
Assuming the machine is freshly rebooted the script:
{{{
/opt/netfpga1.0.1/netfpga/projects/tunneling_openflow_switch/sw/of_start_winlab.sh
}}}

Should be run as root

Known issues:

 1. When Running the of_start_winlab.sh script wake up the netfpga into a tunneling openflow mode we get this error from the script:
    Virtex design compiled against active CPCI version
    {{{
    RTNETLINK answers: No such file or directory
    RTNETLINK answers: No such file or directory
    RTNETLINK answers: No such file or directory
    RTNETLINK answers: No such file or directory
    ARP_REPLY_ETH_ADDR_PORT_3_LO_REG=0x46324402
    }}}
   However it still works.
 1. After a few minutes of operation the nf2 modules starts dumping buffer messages into the kernels ring buffer. The messages are:
    {{{
    [ 1161.690033] nf2: no available transmit/receive buffers
    [ 1161.690061] nf2: no available transmit/receive buffers
    [ 1161.690089] nf2: no available transmit/receive buffers
    }}}
   We don't know what these errors are, and they are suspected to eventually brining down the tunnel (and thus requiring a reboot). That being said,
   the tunnel does come up inspite of it.
 1. The tunnel still dies, when I tried to bring it back up the interfaces took a little time to actually wake up, but it eventually got to
    where it needed to be.
