Some drivers cannot handle multiple retry rates specified by the rc algorithm but instead use their own retry table (for example rt2800). However, if such a device registers itself with a max_rates value of 1 the rc algorithm cannot make use of the extended information the device can provide about retried rates. On the other hand, if a device registers itself with a max_rates value > 1 the rc algorithm assumes that the device can handle multi rate retries. Fix this issue by introducing another hw parameter max_report_rates that can be set to a different value then max_rates to indicate if a device is capable of reporting more rates then specified in max_rates.
