Attached please find two patches for the igb and ixdbe drivers that allow a guest instance to set the MAC address.
To enable such features, you need to run this on the host:
ip link set dev <interface_name> vf < index> spoofchk off
The igb patch is based on version 5.3.3.5.
The ixgbe patch is based on redhat el7 3.10.0.-327.4.5.el7 kernel. (i.e. linux-3.10.0-327.4.5.el7.x86_64/drivers/net/ethernet/intel/ixgbe)
Let me know if that make sense?
Clik here to view.
