[RFC PATCH v1 5/5] dts: add test suite for RX and TX offloads

[jspewock@iol.unh.edu]

From: Jeremy Spewock <jspewock@iol.unh.edu>

This patch adds a test sutie that ports over and expands upon
functionality provided in the RxTx test sutie in Old DTS. This test
suite provides convenience methods and decorators in an attempt to
reduce code duplication when developers are tasked with testing the
same offloaded functionality through 3 different mediums (passed on the
command-line, configured on a port at runtime, and configured on queues
at runtime).

+"""Rx/Tx offload configuration suite.
+
+The goal of this suite is to test the support for three different methods of offloading different
+capabilities using testpmd: On a queue, on a port, and on the command-line. Support for configuring
+the capability through different means is testing alongside verifying the functionality of the
+capability when offloaded. Each of the three methods of setting the capability should be tested
+using the same criteria to monitor for differences between the methods.
+
+Testing consists of enabling the capability if it wasn't passed in through the command-line,
+verifying that the capability performs it's expected task, then, in the general case, disabling the
+capability and verifying that the same result is not achieved in a default state. Some cases do not
+check the base-case since their functionality is enabled by default without offloading the
+capability (like invalid checksum verification, for example).
+
+There should be test cases for each of the 3 configuration strategies for every offload that is
+tested. Additionally, there are two additional test cases that validates the ability to enable
+every offload that a device supports on its port without actually testing the functionality of the
+offload for both Rx and Tx.
