30 * csBeacon_xmit - beacon tx function
31 * csMgmt_xmit - management tx function
32 * s_uGetDataDuration - get tx data required duration
33 * s_uFillDataHead- fulfill tx data duration header
34 * s_uGetRTSCTSDuration- get rtx/cts required duration
35 * s_uGetRTSCTSRsvTime- get rts/cts reserved time
36 * s_uGetTxRsvTime- get frame reserved time
37 * s_vFillCTSHead- fulfill CTS ctl header
38 * s_vFillFragParameter- Set fragment ctl parameter.
39 * s_vFillRTSHead- fulfill RTS ctl header
40 * s_vFillTxKey- fulfill tx encrypt key
41 * s_vSWencryption- Software encrypt header
42 * vDMA0_tx_80211- tx 802.11 frame via dma0
