+Subject: [PATCH 6/7] brcmfmac: add RSDB condition when setting interface
+ combinations
+
+With firmware RSDB feature
+1. The maximum support interface is four.
+2. The maximum difference channel is two.
+3. The maximum interfaces of {station/p2p client/AP} are two.
+4. The maximum interface of p2p device is one.
