In addition, you will actually need to enable CONFIG_IEEE80211R=y to get
this working properly assuming you are using anything older than the
current snapshot from the development tree. It should also be noted that
a configuration that enables only WPA-PSK-SHA256 will be quite limiting
since most (well, more or less all) deployed client devices do not
support it.
