* File: rxtx.c
*
* Purpose: handle WMAC/802.3/802.11 rx & tx functions
*
* Author: Lyndon Chen
*
* Date: May 20, 2003
*
* Functions:
* s_vGenerateTxParameter - Generate tx dma required parameter.
* s_vGenerateMACHeader - Translate 802.3 to 802.11 header
* csBeacon_xmit - beacon tx function
* csMgmt_xmit - management tx function
* 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
* vGenerateFIFOHeader- Generate tx FIFO ctl header
