 In libbpf, the map can be defined with extra annotation like below:
 ::
 
-    struct bpf_map_def SEC("maps") btf_map = {
-        .type = BPF_MAP_TYPE_ARRAY,
-        .key_size = sizeof(int),

+    struct {
+        __uint(type, BPF_MAP_TYPE_ARRAY);

+        __type(value, struct ipv_counts);
+        __uint(max_entries, 4);
+    } btf_map SEC(".maps");
 
-Here, the parameters for macro BPF_ANNOTATE_KV_PAIR are map name, key and
-value types for the map. During ELF parsing, libbpf is able to extract
-key/value type_id's and assign them to BPF_MAP_CREATE attributes
-automatically.
