UNH CI is reporting [0] build errors [1] for 21.11 branch on Arch Linux.
The cause is that libbpf 0.7.0 has been installed and now that af_xdp is
being compiled with that version there are some deprecated calls being used.
This can be fixed by taking some patches from DPDK main branch to use
libxdp.
It will be nice if we can keep it working for users who upgrade
library versions, but the most important is to not cause regressions
for users who do not.
Ciara, please let me know if you see any any issues with these patches
for 21.11 branch?
Reproduced compile failures on F35 with updated library versions without
the patches and passing when patches applied.
Compile tested on F35 with new versions:
Run-time dependency libxdp found: YES 1.2.2
Run-time dependency libbpf found: YES 0.7.0
Also compile tested for regressions on F35 with packaged versions:
Dependency libxdp found: NO found 1.1.0 but need: '>=1.2.2'
Run-time dependency libxdp found: NO (tried pkgconfig)
Run-time dependency libbpf found: YES 0.4.0
thanks,
Kevin.
