| * 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 requried duration |
| * s_uGetRTSCTSRsvTime- get rts/cts reserved time |
| * s_uGetTxRsvTime- get frame reserved time |
| * s_vFillCTSHead- fulfill CTS ctl header |
| * s_vFillFragParameter- Set fragement 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 |
