Enhancements to the TWT attributes/parameters (vendor command)
This commit does the following enhancements to the TWT interface: Corrects the documentation for QCA_WLAN_TWT_SUSPEND and QCA_WLAN_TWT_TERMINATE. Specifies that these operations carry the parameters obtained through QCA_WLAN_VENDOR_ATTR_CONFIG_TWT_PARAMS. This interface is very recently introduced and missed to document the same. There are no user space or driver components using this interface yet. Hence, enhancing/modifying the interface. Corrects the documentation for QCA_WLAN_VENDOR_ATTR_TWT_SETUP_WAKE_DURATION. Mentions that the units it represent is a multiple of 256 microseconds rather than a TU. The host driver always interpreted this as an unit in 256 microseconds and there are no user space implementations that are impacted with this change in the unit. Hence, modifying the documentation. Introduces QCA_WLAN_VENDOR_ATTR_TWT_RESUME_NEXT2_TWT_SIZE, which is similar to that of QCA_WLAN_VENDOR_ATTR_TWT_RESUME_NEXT_TWT, but carries an offset/data of u32 size. Introduces MAC_ADDR attribute to represent the peer for the TWT setup and resume operations. Signed-off-by: Jouni Malinen <jouni@codeaurora.org>
