TAP is a virtual device created on Kernel. The speed of interface is
set by Kernel to a fixed static value. But this does not prevent using
RX or TX to rate limit. Hence removing the option from user arguments.

``iface=foo0``, for example::
--vdev=net_tap0,iface=foo0 --vdev=net_tap1,iface=foo1, ...
-Also the speed of the interface can be changed from 10G to whatever number

Normally the PMD will generate a random MAC address, but when testing or with
a static configuration the developer may need a fixed MAC address style.
Using the option ``mac=fixed`` you can create a fixed known MAC address::
