For p2p/miracast, the wifi may have multiple ports for different roles.
Under this, we need extra settings for turning off the tdma and proper
coex table parameters.
We monnitor the number of links on a port to determine if it is for
p2p/miracast or not.

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.

The power_save_state function checks the state of power saving.
For tdma settings, the wifi sends nullfunc to pretend enter power saving
