Bug description:
Issue description:
Attaching a Legacy network adapter to a VM will not be detected on the VM
side.

Steps to Reproduce:
1. Add a Legacy Network adapter to the VM
2. Boot the vm
3. Verify the identified network adapter, the legacy NIC is missing
Versions details:
Windows Server Host Edition: Microsoft Windows Server 2012 R2 Datacenter
build 9600 and Microsoft Windows Server 2008 R2 Standard SP 1 build 7601
Distribution name and release: Ubuntu Vivid Vervet
Kernel version: Linux ubuntu31 3.19.0-11-generic #11lp14233432v201504021617
SMP
Hyper-V side:
PS> Get-VMNetworkAdapter -VMName vivid1
Name IsManagementOs VMName SwitchName MacAddress Status

Network Adapter False vivid1 external 00155D06332D {Ok}
{IP, fe80::215:5dff:fe06:332d}
Legacy Network Adapter False vivid1 external 00155D063336 {Ok} {}
On the VM Side:
root@ubuntu31:~# ls /sys/class/net/
eth0 lo
eth0 has the MAC of the Network Adapter, which is the synthetic
interface.
This has been verified with also 1 vCPU or with irqbalancer daemon disabled,
as that is a common requirements when using legacy adapters.
