// Procedure:   Transmit one packet 
//
    Description:   	Emily 2006/04/30, For 8190 PCI
				When configure tx descriptor under 8190Pci hardware, reserve the 
				first one descriptor for Firmware Info(not insert, cause the descriptor 
				address nust be contineous). Then, fill descriptor for each packet 
				buffer from the second descriptor. Configure first descriptor and 
				pTcb->nDescUsed++ before set Own bit.

				Joseph 2006/10/13, Revision
				Integrate the procedure of protection mode determination and duration 
				calculation into single function respectively.
				TransmitTcb() handle the information of each MSDU.
				For further improvement, we can add an function like "HandleMPDUInfo"
				to handle specific information of every fragment of MSDU. But now there 
				are only TxTime calculation is specific to each MPDU, so just leave this 
				idea for future extension.
	Return value:
				TransmitTCB returns RT_STATUS_RESOURCE if TransmitTCB occur some error and cannot Tx.
				TransmitTCB returns RT_STATUS_PKT_DROP if The current link was teardown, and need to drop packet here.
				TransmitTCB returns RT_STATUS_SUCCESS if TransmitTCB OK.
