Hi Chengwen,
Is the intention to test ethdev layer or driver?
It is possible to use ring vdev to create a loopback and to test ethdev
layer.
For driver, it can be possible to create physical loopback connection,
or even can implement loopback Rx/Tx burst functions in driver.
Using another host to send/receive packets to DUT (device under test) is
another approach.
What kind of loopback implementation do you have in your mind?
