From: Siva Rebbagondla <[email protected]> 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.
