The update is resctricting below behavior:
1. Maximum 2 vdevs are only supported per mac.
2. Intraband MCC among beaconing entities shall not be supported.
3. Intraband MCC shall be allowed when STA is operating on
   DFS/Passive/LTE avoidance channel.
4. No DFC SCC shall be allowed both in 2-port and 3-port for Auto.
