But this should not avoid the match (?). Is it possible to grow the verbosity level of the device matching process in DPDK? I do not expect any support, I just wanted to use it for sending traffic at 1 Gbps because there are two such cards mostly unused in my computer. I did not plan to use I217-V (in fact, I did not expect much from this integrated NIC and I did not even notice it is an Intel one...).
