The 4.5.1 version was successfully installed and tested on one network card. However, when I changed to another network card, an error message was displayed.

To Reproduce
Successful NIC is "NetXtreme II BCM5709 Gigabit Ethernet"
Failed NIC is "82599 10 Gigabit TN Network Connection"

just use "--xdp" options

Probably Unbuntu 20.04 kernel is too old to support eBPF, which is required for --xdp. Probably we could have a more informative error message.

As shown in my picture, all the software configurations used are the same, the only change is the network card used.

Maybe we can see something in the kernel log. Can you send my contents of /var/log/kern.log? Also, the output of uname -a.
