From: Raja Mani <rmani@xxxxxxxxxxxxxxxx>
For every WMI_SET_HOST_SLEEP_MODE_CMDID command (send from the host),
the firmware sends WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID as
an acknowledgement to the host.
In order to being sync with the firmware, the host has to wait for
this event before going to the suspend state.
This patch adds,
* New command WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID in
WMI event table.
* New WMI function ath6kl_wmi_host_sleep_mode_cmd_prcd_evt_rx()
to process the event.
* New flag HOST_SLEEP_MODE_CMD_PROCESSED in VIF flags to record
the arrival of the event.
