* vGenerateMACHeader - Translate 802.3 to 802.11 header
* cbGetFragCount - Calculate fragment number count
* csBeacon_xmit - beacon tx function
* csMgmt_xmit - management tx function
* s_cbFillTxBufHead - fulfill tx dma buffer header
* s_uGetDataDuration - get tx data required duration

* s_uGetRTSCTSRsvTime- get rts/cts reserved time
* s_uGetTxRsvTime- get frame reserved time
* s_vFillCTSHead- fulfill CTS ctl header
* s_vFillFragParameter- Set fragment ctl parameter.
* s_vFillRTSHead- fulfill RTS ctl header
* s_vFillTxKey- fulfill tx encrypt key
* s_vSWencryption- Software encrypt header
* vDMA0_tx_80211- tx 802.11 frame via dma0
* vGenerateFIFOHeader- Generate tx FIFO ctl header
