Hello!
I think I have one more question.
For most of the platforms we support libbpf 1.0.1 works fine but I noticed
issues with Debian 11 and Ubuntu 20 about enum declarations:
In file included from
/tmp/fastnetmon.build.dir.i2Ak87Hs7Y/fastnetmon/src/xdp_plugin/xdp_collector.cpp:14:
/opt/fastnetmon-community/libraries/libbpf_1_0_1/include/bpf/bpf.h:396:6:
error: use of enum 'bpf_stats_type' without previous declaration
396 | enum bpf_stats_type; /* defined in up-to-date linux/bpf.h */
| ^~~~~~~~~~~~~~

t);

Did you experience similar errors previously by any chance?
Thank you!
