tools/bpf: bpftool: add net support
Add "bpftool net" support. Networking devices are enumerated
to dump device index/name associated with xdp progs.
For each networking device, tc classes and qdiscs are enumerated
in order to check their bpf filters.
In addition, root handle and clsact ingress/egress are also checked for
bpf filters. Not all filter information is printed out. Only ifindex,
kind, filter name, prog_id and tag are printed out, which are good
enough to show attachment information. If the filter action
is a bpf action, its bpf program id, bpf name and tag will be
printed out as well.
For example,
$ ./bpftool net
xdp [
ifindex 2 devname eth0 prog_id 198
]
tc_filters [
ifindex 2 kind qdisc_htb name prefix_matcher.o:[cls_prefix_matcher_htb]
prog_id 111727 tag d08fe3b4319bc2fd act []
ifindex 2 kind qdisc_clsact_ingress name fbflow_icmp
prog_id 130246 tag 3f265c7f26db62c9 act []
ifindex 2 kind qdisc_clsact_egress name prefix_matcher.o:[cls_prefix_matcher_clsact]
prog_id 111726 tag 99a197826974c876
ifindex 2 kind qdisc_clsact_egress name cls_fg_dscp
prog_id 108619 tag dc4630674fd72dcc act []
ifindex 2 kind qdisc_clsact_egress name fbflow_egress
prog_id 130245 tag 72d2d830d6888d2c
]
