+       the 4-way handshake to firmware which is needed for protocols which
+       act on Authenticate/Associate frames such as Fast Transition. This
+       option is turned off by default as it is not widely tested.

+       Note: There seems to be a bug in the brcmfmac driver/firmware where once
+       offloading is enabled (by turning on this option) it cannot be turned
+       off in the firmware without a hard reboot (or some means of restarting
+       the firmware).
