Sure. will look into it. Do you think this will help with the issue you saw with having to change mac on standy twice to get the init scripts working? We are now going to block changing the mac on both standby and failover. Also, i was wondering if we should set dev->flags to IFF_MASTER on failover and IFF_SLAVE on primary and standby. netvsc does this. Does this help with the init scripts and network manager to skip slave devices for dhcp requests?
