Description of problem:

For legacy 32 bit guest OS, VMware have an option of "Vlance" network type[1]. For these devices, we can see the network type as "VirtualPCNet32"  from VMware mob https://<vcenter-url>/mob/?moid=<vm-id>&doPath=config.hardware.device. This interface is not detected by MTV. The forklift inventory of this VM doesn't show any network interface attached to this VM.

# curl -k -X GET -H "Authorization: Bearer $token" https://127.0.0.1:8443/providers/vsphere/423cef6f-efb9-42db-bcbf-8fc335121c58/vms/vm-86359?detail=1 2>/dev/null' |jq '.nics'
[]

So when we migrate this VM, it is created without any network interface. 

Version-Release number of selected component (if applicable):

Migration Toolkit for Virtualization Operator   2.9.5

How reproducible:

Always

Steps to Reproduce:

1. Create a RHEL 5 32 bit VM in VMware. Add the interface with "Adapter Type: Flexible" 
2. Try migrating this VM to OpenShift Virtualization. The VM will be created without any interface in OpenShift Virtualization.

Actual results:

MTV doesn't recognise the VirtualPCNet32 adapter type from VMware

Expected results:

Map it to compatible network driver in OpenShift Virtualization side.
