Hi Anil,
I tested it with Mellanox NIC and it working
16: enp6s0d1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode

I guess the problem is with the SR-IOV NIC/ driver you are using maybe you
should contact them

Miguel,
I talked to our driver architect and according to him this is vendor
implementation (according to him this should work with Mellanox NIC) I need
to verify that this indeed working.
I will update after I will prepare SR-IOV setup and try it myself.

@moshe, any insight on this?
I guess that'd depend on the nic internal switch implementation and how the
switch ARP tables are handled there (per network, or global per switch).
If that's the case for some sr-iov vendors (or all), would it make sense to
have a global switch to create globally unique mac addresses (for the same
neutron deployment, of course).
