From: Siva Rebbagondla <siva.rebbagondla@xxxxxxxxxxxxxxxxxx>
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.
