Add support to dump XDP link information to bpftool. This reuses the
recently added show_link_ifindex_{plain,json}(). The XDP link info only
exposes the ifindex.
Below shows an example link dump output, and a cgroup link is included
for comparison, too:
# bpftool link
[...]
10: cgroup prog 2466
cgroup_id 1 attach_type cgroup_inet6_post_bind
[...]
16: xdp prog 2477
ifindex enp5s0(3)
[...]
Equivalent json output:
# bpftool link --json
[...]
{
"id": 10,
"type": "cgroup",
"prog_id": 2466,
"cgroup_id": 1,
"attach_type": "cgroup_inet6_post_bind"
},
[...]
{
"id": 16,
"type": "xdp",
"prog_id": 2477,
"devname": "enp5s0",
"ifindex": 3
}
[...]
