Why are people spending so much time cleaning up a driver that doesn't work well? With the default module parameters it had 35% packet loss with the router 3 meters away in the same room. With rtw_power_mgnt=0 the packet loss is gone but the speed is still disappointing: less than 50 megabits/second download, 65-70 upload, and it's unsteady. The v5.2.2.4 driver from Larry Finger's repo works much better: no packet loss and a steady 95 and 85 megabits/second in the same conditions. I'll get started then.
