Subject: [PATCH 0/2] net: openvswitch: metering and conntrack in userns

Currently using openvswitch in a non-inital user namespace, e.g., an
unprivileged container, is possible but without metering and conntrack
support. This is due to the restriction of the corresponding Netlink
interfaces to the global CAP_NET_ADMIN.

This simple patches switch from GENL_ADMIN_PERM to GENL_UNS_ADMIN_PERM
in several cases to allow this also for the unprivilegd container
use case.

We tested this for unprivileged containers created by the container
manager of GyroidOS (gyroidos.github.io). However, for other container
managers such as LXC or systemd which provide unprivileged containers
this should be apply equally.

Applies against v6.0-rc4
