Subject: P54usb getting WARN_ON at line 2247 of net/mac80211/rx.c

My system has recently started getting the WARN_ON from routine __ieee80211_rx()
because of a faulty rate_idx value in the following code snippet:

        } else {
                if (WARN_ON(status->rate_idx < 0 ||
                            status->rate_idx >= sband->n_bitrates))
                        return;
                rate = &sband->bitrates[status->rate_idx];
        }

I thought I remembered a patch for this that was circulated, but I couldn't find
it. This warning was logged while using p54usb. It may happen for other drivers
as well, but I have been using only p54usb for the past few days.

Thanks,

Larry
