SELinux is preventing systemd-network from 'create' accesses on the netlink_netfilter_socket labeled systemd_networkd_t.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that systemd-network should be allowed create access on netlink_netfilter_socket labeled systemd_networkd_t by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'systemd-network' --raw | audit2allow -M my-systemdnetwork
# semodule -X 300 -i my-systemdnetwork.pp
