Can be run by passing devargs to SSO PF as follows:

Example:
	--dev "0002:0e:00.0,selftest=1"

+  The functionality of OCTEON TX2 eventdev can be verified using this option,
+  various unit and functional tests are run to verify the sanity.
+  The tests are run once the vdev creation is successfully complete.
+  For example::
