// Description: Switch BW to 40HMz for a specific reason. It only needs to be operate if WoWLAN mode
// 	is enabled and we will call the function in PNP_SET_POWER OID handler.
//	<Note> According to 802.11n spec chapter 11.14.12 "Switching between 40 MHz and 20 MHz",
//		2.4G AP will switch BW (40 <--> 20MHz) in some cases, and we will really switch BW
//		to 20MHz if our BSS AP enable the capability in beacon. It will cause an issue that if we
//		switch BW to 20MHz before the system enters WoWLAN mode, and the AP returns to 40MHz
//		such that we cannot receive 40MHz data and will be deauth by AP in some cases, so we 
//		recover the BW to 40MHz in order to Rx 40MHz data and we should make sure that we will
//		not Tx MCS rate during WoWLAN mode (now we set all the Tx packet rates to 1M, see
//		FillFakeTxDescriptor_XXX().).
