16 *
17 * Purpose: Implement functions to access baseband
18 *
19 * Author: Kyle Hsu
20 *
21 * Date: Aug.22, 2002
22 *
23 * Functions:
24 * BBuGetFrameTime - Calculate data frame transmitting time
25 * BBvCaculateParameter - Caculate PhyLength, PhyService and Phy Signal
26 * parameter for baseband Tx
27 * BBbReadEmbedded - Embedded read baseband register via MAC
28 * BBbWriteEmbedded - Embedded write baseband register via MAC
29 * BBbVT3253Init - VIA VT3253 baseband chip init code
30 *
31 * Revision History:
32 * 06-10-2003 Bryan YC Fan: Re-write codes to support VT3253 spec.
33 * 08-07-2003 Bryan YC Fan: Add MAXIM2827/2825 and RFMD2959 support.
34 * 08-26-2003 Kyle Hsu : Modify BBuGetFrameTime() and
35 * BBvCalculateParameter().
36 * cancel the setting of MAC_REG_SOFTPWRCTL on
37 * BBbVT3253Init().
38 * Add the comments.
39 * 09-01-2003 Bryan YC Fan: RF & BB tables updated.
40 * Modified BBvLoopbackOn & BBvLoopbackOff().
