Hello,
I am trying to use DPDK on a IXGBE port, but whenever I bind the igb_uio
driver to this interface, the interface disappears from the system. DPDK
however shows the interface as attached. I also have the KNI module present
added to the system, as there are some previous threads that suggested that
the interface does not show up because igb_uio driver does not generate
netdev devices.
Following is the log of the operations:
1. `ifconfig` before binding:
