 *      cbGetFragCount - Caculate 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_uFillDataHead- fulfill tx data duration header
 *      s_uGetRTSCTSDuration- get rtx/cts 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
