rsi: optimize virtual interfaces
Due to multiple calls of add interface routine, vif is getting duplicated and at certain instance, we are out of vifs, causing the driver to behave abnormal. Fix: Every vif has a unique mac-id, when we got a vif with same mac-id as the previous id's, we will override the respective vif.
