Presently the roaming design is to support roaming on both the STA in DBS mode (with different bands). With commit I60f6bdb7df4d9eece4fd14abe1fab2d5644d47f1, Driver allow STA2 connection to any available AP(s). So in case if STA2 connectes in MCC mode then host should not allow roaming on non primary STA iface. Change-Id: I84c77644c6023322ac77e307b06be70ec0f58ed5 CRs-Fixed: 2928804
