[PATCH v3 net-next 1/2] net: openvswitch: allow metering in non-initial user namespace

[Michael Weiß]

The Netlink interface for metering was restricted to global CAP_NET_ADMIN
by using GENL_ADMIN_PERM. To allow metring in a non-inital user namespace,
e.g., a container, this is changed to GENL_UNS_ADMIN_PERM.
