[PATCH v2 net 1/2] net: openvswitch: allow metering in non-initial user namespace

From: Michael Weiß
Date: Tue Sep 20 2022 - 21:21:29 EST


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.
