Switching from legacy usage of ieee80211_get_tx_rates() lookup to direct rate table lookup in struct ieee80211_sta->rates. The current rate control API allows drivers to directly get rates from ieee80211_sta->rates. ath5k is currently one of the legacy drivers that perform translation/merge with the internal rate table via ieee80211_get_tx_rates provided by rate control API. For our upcoming changes to rate control API and the implementation of transmit power control, this patch changes the behaviour. The call to ieee80211_get_tx_rates and subsequent calls are also avoided. ath5k now directly reads rates from sta->rates into its internal rate table. Cause ath5k does not rely on the rate array in SKB->CB, this is not considered anymore except for the first entry (used for probing). Tested this on a PCEngines ALIX with CMP9-GP miniPCI wifi card (Atheros AR5213A). Generated traffic between AP and multiple STAs before and after applying the patch and simultaneously measured throughput and captured rc_stats. Comparison resulted in same rate selection and no performance loss between both runs.
