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.
