rtlwifi: btcoex: 21a 2ant: action for wifi is idle/linking/common
Depending on the state of wifi, we need to set different tdma and coex table parameters to make wfi and bt coexist smoothly. Otherwise the bt may have low sound quality or mouse lag, which mean bad user experience. The same problem may occur on wifi also, if could disconnect or lose some important packets.
