 * 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.
 *      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_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
