Subject: [PATCH bpf-next] libbpf: use AF_LOCAL instead of AF_INET in xsk.c

From: Stanislav Fomichev <[email-masked]>
Date: Tue, 9 Feb 2021 14:18:26 -0800

We have the environments where usage of AF_INET is prohibited
(cgroup/sock_create returns EPERM for AF_INET). Let's use
AF_LOCAL instead of AF_INET, it should perfectly work with SIOCETHTOOL.
