Hi Vivek,
You can ignore the 'Generic Netlink family' error, as you've mentioned.
From the output of dpdk_nic_bind, I can see that you're using the in-kernel
standard IXGBE driver - you'll need to use one of the kernel drivers from the
DPDK codebase to use a DPDK-compatible NIC with OVS-DPDK:
e.g. (for IGB_UIO driver)
- modprobe uio
- insmod $RTE_SDK/$RTE_TARGET/kmod/igb_uio.ko
- $RTE_SDK/tools/dpdk_nic_bind.py -b <PCI_IDs of NIC ports> igb_uio
- check that driver has bound successfully:
$RTE_SDK/tools/dpdk_nic_bind.py --s
- kick off test setup as normal
Btw, and on a completely separate point, could you remove the company signature
at the end of your mail, as it's redundant on an Open Source mailing list?
Thanks,
Mark
