* Store macid and color values in struct iwm_vap, to avoid hardcoded constants a bit. * Add iwm_mvm_binding_remove_vif() function (will be used in disconnecting from an access point without resetting the whole device). * Not adding code from Linux iwlwifi yet, to handle one PHY context to be bound to several VAPs/virtual-interfaces, it's definitely not needed in the near future.
