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.
