I believe you have confused my comments with others. My comments have focused on one aspect: The insistence by BPF maintainers that all code bases and users constantly chase latest and greatest versions of relevant S/W to use BPF - though I believe a lot of the tool chasing stems from BTF. I am fairly certain I have been consistent in that theme within this thread. > when myself, Daniel, Andrii explained in detail what libbpf does and how it > affects user experience? > > The analogy of libbpf in iproute2 and libbfd in gdb is that both libraries Your gdb / libbfd analogy misses the mark - by a lot. That analogy is relevant for bpftool, not iproute2. iproute2 can leverage libbpf for 3 or 4 tc modules and a few xdp hooks. That is it, and it is a tiny percentage of the functionality in the package.
