Bitterblue Smith 5368db4d7e wifi: rtl8xxxu: Use a longer retry limit of 48 ... commit 2a86aa9a18 upstream. The Realtek rate control algorithm goes back and forth a lot between the highest and the lowest rate it's allowed to use. This is due to a lot of frames being dropped because the retry limits set by IEEE80211_CONF_CHANGE_RETRY_LIMITS are too low. (Experimentally, they are 4 for long frames and 7 for short frames.) The vendor drivers hardcode the value 48 for both retry limits (for station mode), which makes dropped frames very rare and thus the rate control is more stable. Because most Realtek chips handle the rate control in the firmware, which can't be modified, ignore the limits set by IEEE80211_CONF_CHANGE_RETRY_LIMITS and use the value 48 (set during chip initialisation), same as the vendor drivers.
