the meter color result:
``color type (green|yellow|red)``.
* **Added support for the FIB lookup method in the l3fwd example app.**
Added support to the l3fwd application to support
the Forwarding Information Base (FIB) lookup method.
Previously l3fwd only supported the LPM and Exact Match lookup methods.
* **Updated the ipsec-secgw sample application.**
* Updated the ``ipsec-secgw`` sample application with UDP encapsulation
support for NAT Traversal.
* **Added sub-testsuite support.**
* The unit test suite struct now supports having both a nested
list of sub-testsuites, and a list of testcases as before.
Removed Items
-------------
* Removed support for Intel DLB V1 hardware. This is not a broad market device,
and existing customers already obtain the source code directly from Intel.
API Changes
-----------
* eal: The experimental TLS API added in ``rte_thread.h`` has been renamed
from ``rte_thread_tls_*`` to ``rte_thread_*`` to avoid naming redundancy
and confusion with the transport layer security term.
* pci: The value ``PCI_ANY_ID`` is marked as deprecated
and can be replaced with ``RTE_PCI_ANY_ID``.
* ethdev: Added a ``rte_flow`` pointer parameter to the function
``rte_flow_dev_dump()`` allowing dumping of a single flow.
* cryptodev: The experimental raw data path API for dequeue
``rte_cryptodev_raw_dequeue_burst`` got a new parameter
``max_nb_to_dequeue`` to provide flexible control on dequeue.
* ethdev: The experimental flow API for shared action has been generalized
as a flow action handle used in rules through an indirect action.
The functions ``rte_flow_shared_action_*`` manipulating the action object
are replaced with ``rte_flow_action_handle_*``.
The action ``RTE_FLOW_ACTION_TYPE_SHARED`` is deprecated and can be
replaced with ``RTE_FLOW_ACTION_TYPE_INDIRECT``.
* ethdev: The experimental function ``rte_mtr_policer_actions_update()``,
the enum ``rte_mtr_policer_action``, and the struct members
``policer_action_recolor_supported`` and ``policer_action_drop_supported``
have been removed.
* vhost: The vhost library currently populates received mbufs from a virtio
driver with Tx offload flags while not filling Rx offload flags.
While this behavior is arguable, it is kept untouched.
A new flag ``RTE_VHOST_USER_NET_COMPLIANT_OL_FLAGS`` has been added to ask
for a behavior compliant with the mbuf offload API.
* stack: Lock-free ``rte_stack`` no longer silently ignores push and pop when
it's not supported on the current platform. Instead ``rte_stack_create()``
fails and ``rte_errno`` is set to ``ENOTSUP``.
* raw/ioat: The experimental function ``rte_ioat_completed_ops()`` now
supports two additional parameters, ``status`` and ``num_unsuccessful``,
to allow the reporting of errors from hardware when performing copy
operations.
ABI Changes
-----------
* No ABI change that would break compatibility with 20.11.
* The experimental function ``rte_telemetry_legacy_register`` has been
removed from the public API and is now an internal-only function. This
function was already marked as internal in the API documentation for it,
and was not for use by external applications.
