Description of problem:
SELinux is preventing NetworkManager from 'create' accesses on the netlink_generic_socket Unknown.

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

If you believe that NetworkManager should be allowed create access on the Unknown netlink_generic_socket by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep NetworkManager /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
