Hi Julia, 

I intend to do it on all of those functions. However, I'm avoiding big
patch sets for now. To fix all then it will require at least 18 patches
in a set:

* Functions:
  0  *      s_vGenerateTxParameter - Generate tx dma required parameter.
  1  *      vGenerateMACHeader - Translate 802.3 to 802.11 header
  2  *      cbGetFragCount - Calculate fragment number count
  3  *      csBeacon_xmit - beacon tx function
  4  *      csMgmt_xmit - management tx function
  5  *      s_cbFillTxBufHead - fulfill tx dma buffer header
  6  *      s_uGetDataDuration - get tx data required duration
  7  *      s_uFillDataHead- fulfill tx data duration header
  8  *      s_uGetRTSCTSDuration- get rtx/cts required duration
  9  *      get_rtscts_time- get rts/cts reserved time
 10  *      s_uGetTxRsvTime- get frame reserved time
 11  *      s_vFillCTSHead- fulfill CTS ctl header
 12  *      s_vFillFragParameter- Set fragment ctl parameter.
 13  *      s_vFillRTSHead- fulfill RTS ctl header
 14  *      s_vFillTxKey- fulfill tx encrypt key
 15  *      s_vSWencryption- Software encrypt header
 16  *      vDMA0_tx_80211- tx 802.11 frame via dma0
 17  *      vGenerateFIFOHeader- Generate tx FIFO ctl header
 18  *
 19  * Revision History:

 Thanks.
