consistent with existing outer header checksum status flag naming, which
should help in reducing confusion about its usage.
-* i40e: As there are both i40evf and iavf pmd, the functions of them are
- duplicated. And now more and more advanced features are developed on iavf.
- To keep consistent with kernel driver's name
- (https://patchwork.ozlabs.org/patch/970154/), i40evf is no need to maintain.
- Starting from 21.05, the default VF driver of i40e will be iavf, but i40evf
- can still be used if users specify the devarg "driver=i40evf". I40evf will
- be deleted in DPDK 21.11.
-
* net: ``s_addr`` and ``d_addr`` fields of ``rte_ether_hdr`` structure
will be renamed in DPDK 21.11 to avoid conflict with Windows Sockets headers.
data length so that driver/HW can write expanded size data after encryption.
This change is targeted for DPDK 21.11.
-* cryptodev: The interface between library and drivers will be marked
- as internal in DPDK 21.11.
+* cryptodev: Hide structures ``rte_cryptodev_sym_session`` and
+ ``rte_cryptodev_asym_session`` to remove unnecessary indirection between
+ session and the private data of session. An opaque pointer can be exposed
+ directly to application which can be attached to the ``rte_crypto_op``.
* security: Hide structure ``rte_security_session`` and expose an opaque
pointer for the private data to the application which can be attached
to the packet while enqueuing.
-* security: The IPsec configuration structure
- ``struct rte_security_ipsec_xform`` will be updated with new members to allow
- SA lifetime configuration. A new structure would be introduced to replace the
- current member, ``esn_soft_limit``.
+* security: The structure ``rte_security_ipsec_xform`` will be extended with
+ multiple fields: source and destination port of UDP encapsulation,
+ IPsec payload MSS (Maximum Segment Size), and ESN (Extended Sequence Number).
* security: The IPsec SA config options ``struct rte_security_ipsec_sa_options``
will be updated with new fields to support new features like IPsec inner
- checksum, tunnel header verification, TSO in case of protocol offload.
+ checksum, TSO in case of protocol offload.
+
+* ipsec: The structure ``rte_ipsec_sa_prm`` will be extended with a new field
+ ``hdr_l3_len`` to configure tunnel L3 header length.
* eventdev: The file ``rte_eventdev_pmd.h`` will be renamed to ``eventdev_driver.h``
to make the driver interface as internal and the structures ``rte_eventdev_data``,
* cmdline: ``cmdline`` structure will be made opaque to hide platform-specific
content. On Linux and FreeBSD, supported prior to DPDK 20.11,
original structure will be kept until DPDK 21.11.
-
-* security: The functions ``rte_security_set_pkt_metadata`` and
- ``rte_security_get_userdata`` will be made inline functions and additional
- flags will be added in structure ``rte_security_ctx`` in DPDK 21.11.
-
-* cryptodev: The structure ``rte_crypto_op`` would be updated to reduce
- reserved bytes to 2 (from 3), and use 1 byte to indicate warnings and other
- information from the crypto/security operation. This field will be used to
- communicate events such as soft expiry with IPsec in lookaside mode.
