As I know currently not, but any patches are welcome :)
Do you guys wants to use it in test env?

I know that it would be helpful in development, but for testing, it
would be have a remote access to DUT.

As I said, it only happens in develop mode, while for automation
testing, it would be unacceptable to have no other NIC for control patch.

Or it would be reasonable to add one serial port to control it in
testing mode.

I have a patch send out maybe can solve this, but I have not checked yet

This failure maybe because you only have one NIC port :), but two needs.
