//
// 20100514 Luke/Joseph:
// Add new function for antenna diversity after link.
// This is the main function of antenna diversity after link.
// This function is called in HalDmWatchDog() and ODM_SwAntDivChkAntSwitchCallback().
// HalDmWatchDog() calls this function with SWAW_STEP_PEAK to initialize the antenna test.
// In SWAW_STEP_PEAK, another antenna and a 500ms timer will be set for testing.
// After 500ms, ODM_SwAntDivChkAntSwitchCallback() calls this function to compare the signal just
// listened on the air with the RSSI of original antenna.
// It chooses the antenna with better RSSI.
// There is also a aged policy for error trying. Each error trying will cost more 5 seconds waiting
// penalty to get next try.
//
//
// 20100503 Joseph:
// Add new function SwAntDivCheck8192C().
// This is the main function of Antenna diversity function before link.
// Mainly, it just retains last scan result and scan again.
// After that, it compares the scan result to see which one gets better RSSI.
// It selects antenna with better receiving power and returns better scan result.
//
//
// 20100514 Luke/Joseph:
// This function is used to gather the RSSI information for antenna testing.
