This new member is used for 160Mhz related configuration. This WMI command mismatch between host and firmware does not cause any real issues because this new member is not used in 10.4 firmwares so far (10.4.1.00030-1). This difference in WMI command interface brings in a new wmi_ops for 10.4 gen_peer_assoc(). No noticeable functionality differences with this change can be seen with the current 10.4 firmwares, but the WMI interface has to be fixed to work with future 10.4 firmwares which may be using this new member.
