Subject: libbpf: Recognize SK_REUSEPORT programs from section name
Patch-mainline: v5.6-rc1
Git-commit: 67d69ccdf389f3b7fabb00e2d81473a915b3b64d
References: bsc#1177028
Allow loading BPF object files that contain SK_REUSEPORT programs without
having to manually set the program type before load if the the section name
is set to "sk_reuseport".
Makes user-space code needed to load SK_REUSEPORT BPF program more concise.
