Re: [dts] [patch V1] tests: add testsuite virtio user as exceptional path

["Tu, Lijuan" <lijuan.tu@intel.com>]

I am confused, your goal is to test virtio_user_as_exceptional_path, but you want to use GRO configuration file.

If I am not very familiar with your script, it's very easy to misunderstand it.
