+ * WMI event receiving - theory of operations
+ *
+ * When firmware about to report WMI event, it fills memory area
+ * in the mailbox and raises misc. IRQ. Thread interrupt handler invoked for
+ * the misc IRQ, function @wmi_recv_cmd called by thread IRQ handler.
+ *
+ * @wmi_recv_cmd reads event, allocates memory chunk  and attaches it to the
+ * event list @wil->pending_wmi_ev. Then, work queue @wil->wmi_wq wakes up
+ * and handles events within the @wmi_event_worker. Every event get detached
+ * from list, processed and deleted.
+ *
+ * Purpose for this mechanism is to release IRQ thread; otherwise,
+ * if WMI event handling involves another WMI command flow, this 2-nd flow
+ * won't be completed because of blocked IRQ thread.

 1. This driver uses the same unregistered vendor id that the firewire core does
      (0xd00d1e). Perhaps this could be exposed as a define in
-     firewire-constants.h?
-2. MAX_ASYNC_PAYLOAD needs to be publicly exposed by core/ohci
-   - otherwise how will this driver know the max size of address window to
-     open for one packet write?
+     firewire.h?
 3. Maybe device_max_receive() and link_speed_to_max_payload() should be
      taken up by the firewire core?
-4. To avoid dropping rx data while still limiting the maximum buffering,
-     the size of the AR context must be known. How to expose this to drivers?
-5. Explore if bigger AR context will reduce RCODE_BUSY responses
