Hi Ray,
The eth1 is real NIC，not a tap device.
Here is the information about host-eth1:
DBGvpp# show hardware

Hi xyxue,
Not sure that `set interface mac addr` will work with af_packet.
Can you provide a little bit more information ...
Are eth1 device's real NICs, or are they Tap devices connected to a
bridge. In the case of a bridge, I presume its a Linux Kernel bridge?
