Right now there is no way to query whether BPF flow_dissector program
is attached to a network namespace or not. In previous commit, I added
support for querying that info, show it when doing `bpftool net`:
$ bpftool prog loadall ./bpf_flow.o \

Right now there is no way to query whether BPF flow_dissector program
is attached to a network namespace or not. In previous commit, I added
support for querying that info, show it when doing `bpftool net`:
$ bpftool prog loadall ./bpf_flow.o \
/sys/fs/bpf/flow type flow_dissector \
