libbpf: Add link-based API for netkit

2023-10-24T23:06:58Z

This adds bpf_program__attach_netkit() API to libbpf. Overall it is very similar to tcx. The API looks as following: LIBBPF_API struct bpf_link * bpf_program__attach_netkit(const struct bpf_program *prog, int ifindex, const struct bpf_netkit_opts *opts); The struct bpf_netkit_opts is done in similar way as struct bpf_tcx_opts for supporting bpf_mprog control parameters. The attach location for the primary and peer device is derived from the program section "netkit/primary" and "netkit/peer", respectively.

libbpf: Add ring__avail_data_size

2023-09-25T23:22:42Z

Add ring__avail_data_size for querying the currently available data in the ringbuffer, similar to the BPF_RB_AVAIL_DATA flag in bpf_ringbuf_query. This is racy during ongoing operations but is still useful for overall information on how a ringbuffer is behaving.
