nl80211: support the MAC80211_HWSIM netlink protocol family
The mac80211_hwsim module exposes a custom generic netlink family for
managing simulated phys and userspace data frame transmission.
Since hwsim functionality is closely related to nl80211 and useful to
e.g. manage simulated wireless testbeds, I decided to include support
directly into the nl80211 module.
Example calls for creating and destroying hwsim wiphys:
nl80211.request(nl80211.const.HWSIM_CMD_NEW_RADIO, 0, {
perm_addr: "02:11:22:33:44:55",
support_p2p_device: true
});
nl80211.request(nl80211.const.HWSIM_CMD_DEL_RADIO, 0, {
radio_name: "phy2"
});
