The Mellanox > documentation talks about unbinding and re-binding the VF. Correct.. I thought you've already done that. So basically the flow is as follow: 1. Create VFs on the hypervisor 2. Configure MAC addresses to the VFs on the Hypervisor 3. Unbind the VFs drivers 4. Bind back This way, the VFs will reload with the configured data.. > The odd > thing is that the MAC for the VF under the parent adapter is '0', but > the othadapter itself has a MAC address.
