Subject: Re: [PATCH v2 0/2] hv_netvsc: associate VF and PV device by serial
 number

From: Stephen Hemminger <stephen@...workplumber.org>

> The Hyper-V implementation of PCI controller has concept of 32 bit serial number
> (not to be confused with PCI-E serial number).  This value is sent in the protocol
> from the host to indicate SR-IOV VF device is attached to a synthetic NIC.
> 
> Using the serial number (instead of MAC address) to associate the two devices
> avoids lots of potential problems when there are duplicate MAC addresses from
> tunnels or layered devices.
