libbpf v0.8.0 deprecates the bpf_get_link_xdp_id and bpf_set_link_xdp_fd

so, use
the recommended replacement functions bpf_xdp_query_id, bpf_xdp_attach
and bpf_xdp_detach which are available to use since libbpf v0.7.0.
Also prevent linking with libbpf versions > v0.8.0.

Hi Andrew/Qi (assuming Ciara is still out of office),
I am seeing a similar issue [1] on 21.11 branch with Fedora 37
(libbpf-0.8.0-2.fc37.x86_64 and libxdp-1.2.6-1.fc37.x86_64).
This patch alone won't apply as there are other dependencies. Looking at
the commits in main branch, it seems like I could take all these [2] to
resolve the issue. With these cherry-picked the build warnings on Fedora
37 are removed.
It's a bit late to take these for DPDK 21.11.3 as I intend to release
later today/tomorrow, so it can be resolved for DPDK 21.11.4.
Do the commits below look ok for backport? Main branch might be able to
demand user uses new libbpf/libxdp versions etc, but with stable we
never want to break the users existing setup when they upgrade from
2X.11.n to 2X.11.n+1.
N.B. ^^^^
Let me know what you think?
IMO these patches are to to be backported to stable branch.
Thanks Andrew.
However, af_xdp maintainers opinion is more important here.
Qi, what do you think?
Hi Qi/Ciara, this issue is still present approaching 21.11.4.
What is your opinion on backporting these patches? Please especially
note the paragraph above wrt users not being required to upgrade libbpf.
+Shibin, following discussion in DPDK release meeting.
thanks,
Kevin.
thanks,
Kevin.
