/*
========================================================================
Routine Description:
Initialize Multi-BSS function.
Arguments:
pAd points to our adapter
pDevMain points to the main BSS network interface
Return Value:
None
Note:
1. Only create and initialize virtual network interfaces.
2. No main network interface here.
3. If you down ra0 and modify the BssNum of RT2860AP.dat/RT2870AP.dat,
it will not work! You must rmmod rt2860ap.ko and lsmod rt2860ap.ko again.
