Comment 1 for bug 1831254

For testing, the git repo is here https://github.com/Netronome/bpf-samples.git

To use it:
$ ./xdpdump -i eth1 -S

The -S says to use xdp generic (versus HW offload which we don't support).

If you don't have the fix, only the slow path packets (TCP SYN, ARP, etc) will show up.
If you have the fix then all packets show up.
