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

[Michael Weiß]

Similar to the previous commit, the Netlink interface of the OVS
conntrack module was restricted to global CAP_NET_ADMIN by using
GENL_ADMIN_PERM. This is changed to GENL_UNS_ADMIN_PERM to support
unprivileged containers in non-initial user namespace.
