I think these hard-coded eventdev names need to be removed from the testing framework, and we should let the app/test >> propt accept the name of the vdev to use instead. That would allow running tests on each device by:

RTE>> eventdev_common_autotest event_skeleton0

RTE>> eventdev_common_autotest event_sw0

Same issue as above, compile-time selection of the tests to be run isn't flexible enough to allow testing multiple eventdevs.
I think using a parameter to eventdev_common_autotest to pass the "name" to use would work again? I am open to other solutions if there's a better way :)
