Abstract:
Support multi-BSS function.
Note:
1. Call RT28xx_MBSS_Init() in init function and
call RT28xx_MBSS_Remove() in close function
2. MAC of different BSS is initialized in APStartUp()
3. BSS Index (0 ~ 15) of different rx packet is got in
APHandleRxDoneInterrupt() by using FromWhichBSSID = pEntry->apidx;
Or FromWhichBSSID = BSS0;
4. BSS Index (0 ~ 15) of different tx packet is assigned in
rt28xx_send_packets() by using RTMP_SET_PACKET_NET_DEVICE_MBSSID()
5. BSS Index (0 ~ 15) of different BSS is got in APHardTransmit() by using
RTMP_GET_PACKET_IF()
6. BSS Index (0 ~ 15) of IOCTL command is put in pAd->OS_Cookie->ioctl_if
7. Beacon of different BSS is enabled in APMakeAllBssBeacon() by writing 1
to the register MAC_BSSID_DW1
8. The number of MBSS can be 1, 2, 4, or 8
