Hi Our DPDK application interfaces with an Intel X722 NIC. We use the IGB UIO module.
We now need to interface to a different NIC (on a custom FPGA). I've been asked to connect to it using IGB UIO but have been told we may need to use i40e PMD instead. I don't understand whether IGB UIO and i40e PMD are the same or different layers. Are they interchangeable or does one use them together? I also note that dpdk_setup.sh offers to install IGB UIO, VFIO and KNI modules but does not mention i40e PMD. Why is this? Sorry for my ignorance. Any explanation would be appreciated. BR David
