[dpdk-dev] [PATCH v2 06/11] event/octeontx: add selftest to device arguments

[Pavan Nikhilesh <pbhagavatula@caviumnetworks.com>]

Add selftest as a device argument that can be enabled by suppling
'self_test=1' as a vdev parameter

	--vdev="event_octeontx,self_test=1"

The selftest is run after vdev creation is successfully
complete.
