25  * The operational mode (a.k.a. op_mode) is the layer that implements
27  * the transport API to access the HW. The op_mode doesn't need to know how the
30  * There can be several op_mode: i.e. different fw APIs will require two
31  * different op_modes. This is why the op_mode is virtualized.
39  *	1) The driver layer (iwl-drv.c) chooses the op_mode based on the
41  *	2) The driver layer starts the op_mode (ops->start)
42  *	3) The op_mode registers mac80211

44  *	5) The driver layer stops the op_mode
48  * struct iwl_op_mode_ops - op_mode specific operations
50  * The op_mode exports its ops so that external components can start it and
57  * @start: start the op_mode. The transport layer is already allocated.
59  * @stop: stop the op_mode. Must free all the memory allocated.
61  * @rx: Rx notification to the op_mode. rxb is the Rx buffer itself. Cmd is the
