29 		  A bpf iterator combines a kernel iterating of
31 		  and a bpf program called for each kernel data object
35 		  The *pin* command creates a bpf iterator from *OBJ*,
41 		  Map element bpf iterator requires an additional parameter
42 		  *MAP* so bpf program can iterate over map elements for
43 		  that map. User can have a bpf program in kernel to run
47 		  User can then *cat PATH* to see the bpf iterator output.
58 **# bpftool iter pin bpf_iter_netlink.o /sys/fs/bpf/my_netlink**
62    Create a file-based bpf iterator from bpf_iter_netlink.o and pin it
63    to /sys/fs/bpf/my_netlink
65 **# bpftool iter pin bpf_iter_hashmap.o /sys/fs/bpf/my_hashmap map id 20**
69    Create a file-based bpf iterator from bpf_iter_hashmap.o and map with
70    id 20, and pin it to /sys/fs/bpf/my_hashmap
