[RFC 0/5] pc: support user provided NIC naming/indexing

[Igor Mammedov]

Series implements support for 'onboard' naming scheme for network
interfaces (1), which is based on PCI firmware spec and lets user
to explicitly specify index that will be used by guest to name
network interface, ex:
    -device e1000,acpi-index=33
should make guest rename NIC name to 'eno33' where 'eno' is default
prefix for this scheme.

Hope is that it will allow to simplify launching VMs from
template disk images with different set VM configurations
without need to reconfigure guest network intrfaces or
risk of loosing network connectivity.

For more detailed description/examples see patches [3-4/5]
