Did you enable accelerated networking? Accelerated networking enables
two interfaces, eth0 will talk to the host via the Hyper-V device
driver, and the new interface would be associated with accelerated
network, an SRIOV interface to the netork card on the host. Continue to
use eth0 as it is the master of both interfaces because they represent
the same NIC. If the SRIOV path were to be rescinded the synthetic path
will remain to keep your network up and running. The mechanism by which
the two interfaces are connected is called "transparent SRIOV".

Ubuntu images in Azure are automatically whitelisted for Accelerated
Networking, but the 4.4 kernel does not support it. Linux-azure,
however, does.
