Hi,
It seems DPDK is not compatible with libbpf 0.8:

From af_xdp documentation (doc.dpdk.org/guides/nics/af_xdp.html):
5.2. Prerequisites
This is a Linux-specific PMD, thus the following prerequisites apply:
Both libxdp >=v1.2.2 and libbpf libraries installed, or, libbpf <=v0.6.0

I am in the first case: libxdp-1.2.3 and libbpf-0.8
According to the documentation, it should work.

I submitted a fix to prevent linking with >=v0.8.0.
It can be used until the more robust solution is ready which requires a bit more validation.
