[PATCH v3 0/9] Testpmd code cleanup

[David Marchand <david.marchand@redhat.com>]

Here is a series to reduce code duplication in testpmd.

This work started from looking at Robin series on reporting lcore busy
cycles in telemetry, which is then added in testpmd [1].
While looking at the forward engines code, I saw way too much
duplicated code.

Warning: this is only compile tested.
