Kernel panic when running this kernel on Ubuntu 1604 on HyperV with Mellanox CX3 SR-IOV enabled. Could you please build a test kernel based on this one (test kernel 4.4.0-65):

So names, such as VF NIC names, that include domain number as part of the name, can be shorter than that based on part of bus UUID previously. The new names will also stay same for VMs created with copied VHD and same number of devices. This is needed for SR-IOV in Azure.
