wifi: mac80211: add vif link addition/removal
Add the necessary infrastructure, including a new driver method, to add/remove links to/from an interface. Also add the missing link address to bss_conf (which we use as link_conf too), and fill it, in station mode for now just randomly, in AP mode we get the address from cfg80211 since the link must be created with an address first. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
