2.6.32-stable review patch. If anyone has any objections, please let us know.

------------------

From: Stanislaw Gruszka <sgruszka(a)redhat.com>

commit 76f273640134f3eb8257179cd5b3bc6ba5fe4a96 upstream.

If AP do not provide us supported rates before assiociation, send
all rates we are supporting instead of empty information element.

v1 -> v2: Add comment.
