Description
===========
Nova update the MAC of the direct-physical port based on the MAC of the PF selected during the initial boot of the VM. But Nova does not update the MAC when the VM is migrated to another compute and therefore using another PF.
Steps to reproduce
==================
Needs a multi node devstack with available SRIOV PFs.
