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.
Andrew Bailey (3):
dts: add TX offload capabilities to NIC capabilities
dts: allow mbuf_fast_free to be set with testpmd shell
dts: update tx_offload test from old dts

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.
