This patch set enables user namespaces having CAP_NET_ADMIN to manage
wiphy devices and create/destroy hwsim radios.
The first patch allows a caller from a non-initial user namespace to run
privileged nl80211 phy/dev operations. The second patch enables hwsim
radio management over Netlink from such namespaces. Together, with these
patches an unprivileged test environment can create user/network
namespaces and set up abitrary simulated wireless networks.
Changes from v1:
* Use a simple counter in hwsim to assign netgroups to net namespaces.
* Store hwsim net_generic() data in a struct, add accessors.
* On namespace exit, do not destroy hwsim radios originally created in
the initial network namespace.
