The AR9485 chip and AR933x SoC both implement LNA diversity. There are a few extra things that need to happen before this can be flipped on for those chips (mostly to do with setting up the different bias values and LNA1/LNA2 RSSI differences) but the first stage is putting this code into the driver layer so it can be reused. This has the added benefit of making it easier to expose configuration options and diagnostic information via the ioctl API. That's not yet being done but it sure would be nice to do so. Tested: * AR9285, with LNA diversity enabled * AR9285, with LNA diversity disabled in EEPROM
