[PATCH v6 0/3] dts: add tx_offload support in dts

[Andrew Bailey]

This patchset introduces the support for Tx offload configuration
through DTS, allowing test cases to be written utilizing Tx offload
capabilities. Along with configuring these capabilities, they are also
added to the NIC capabilities class, in which they can be required by
test suites. Finally, a test suite was created using the aforementioned
changes to update the Rx\Tx offload test suite in legacy DTS.

v2:
* Removed mentions of mbuf_fast_free being configured for Rx queues/ports
  as this is not accurate behaviour.
* Clarify argument descriptions in docstrings.
v3:
* Added seperation between port and queue capabilites as it is relevant
  to the added test case that queues support mbuf fast free
  configuration.
* Homogenized methods for getting Rx and Tx offload capabilities and
  configurations
* Moved to use the text parser to gather the configuration, rather than
  returning the raw string output.
* Updated test suites to use the new ports/queues offload flags in the
  requires decorator
* Updated mbuf fast free test suite to test ports and queues
  individually. Along with updating the way it confirms the
  configuration to be consistent with the new process of getting the
  configuration.
* Moved the get configuration method to the get nic capability patch as
  it is more relevant to that patches context.
v4:
* Cleaned up some typing issues in testpmd, and moved where prefixes
  are passed to the capability flags.
* Added documentation page for test suite.
* Removed use of optional in the added test suite.
v5:
* Moved configuration and capability handling to proper files in the
  api directory.
* Updated Tx capability flags to adhere to the new way of handling them.
* Test suites no longer need to worry about using the flag prefixes when
  analyzing offload configurations, but will still need to for required
  capabilities.
