[dpdk-dev] [PATCH v2 4/4] rawdev: pass device id as parameter to selftest

[Bruce Richardson]

When running self-tests, the driver needs to know the device on which to
run the tests, so we need to take the device ID as parameter. Only the
skeleton driver is providing this selftest capability right now, so we can
easily update it for this change.

Since this change only affects the internals of the drivers, it's not an
ABI or API change
