    Subject[130/140] mac80211: fix supported rates IE if AP doesnt give us its rates
    2.6.33-stable review patch.  If anyone has any objections, please let us know.

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

    From: Stanislaw Gruszka <sgruszka@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.
