*_block() apis from patch 3 and 4 are not covered by this selftest.
Why were they added ? And how were they tested?
Pls trim your cc. bpf@vger and netdev@vger would have been enough.
My main concern with this set is that it adds netlink apis to libbpf while
we already agreed to split xdp manipulation pieces out of libbpf.
It would be odd to add tc apis now only to split them later.
I think it's better to start with new library for tc/xdp and have
libbpf as a dependency on that new lib.
For example we can add it as subdir in tools/lib/bpf/.
Similarly I think integerating static linking into libbpf was a mistake.
It should be a sub library as well.
If we end up with core libbpf and ten sublibs for tc, xdp, af_xdp, linking,
whatever else the users would appreciate that we don't shove single libbpf
to them with a ton of features that they might never use.
