The issue is discovered for bpf selftest test_skb_cgroup.sh.
Currently we have,
$ ./test_skb_cgroup_id.sh
Wait for testing link-local IP to become available ... OK
Object has unknown BTF type: 13!
[PASS]
In the above the BTF type 13 refers to BTF kind
BTF_KIND_FUNC_PROTO.
This patch added support of BTF_KIND_FUNC_PROTO and
BTF_KIND_FUNC during type parsing.
With this patch, I got
$ ./test_skb_cgroup_id.sh
Wait for testing link-local IP to become available ... OK
[PASS]
