Deprecation Notices
|
|
-------------------
|
|
|
|
* Significant ABI changes are planned for struct rte_eth_dev to support up to
|
|
1024 queues per port. This change will be in release 2.2.
|
|
There is no backward compatibility planned from release 2.2.
|
|
All binaries will need to be rebuilt from release 2.2.
|
|
|
|
* The Macros RTE_HASH_BUCKET_ENTRIES_MAX and RTE_HASH_KEY_LENGTH_MAX are
|
|
deprecated and will be removed with version 2.2.
|
|
|
|
* The function rte_jhash2 is deprecated and should be removed.
|
|
|
|
* The following fields have been deprecated in rte_eth_stats:
|
|
imissed, ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
|
|
tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff
|
|
|
|
* API for flow director filters has been replaced by rte_eth_dev_filter_ctrl.
|
|
Following old API is deprecated and will be removed with version 2.2 without
|
|
backward compatibility.
|
|
Functions: rte_eth_dev_fdir_*.
|
|
Structures: rte_fdir_*, rte_eth_fdir.
|
|
Enums: rte_l4type, rte_iptype.
|
|
|
|
* ABI changes are planned for struct rte_eth_fdir_flow_ext in order to support
|
|
flow director filtering in VF. The release 2.1 does not contain these ABI
|
|
changes, but release 2.2 will, and no backwards compatibility is planned.
|
|
|
|
* ABI changes are planned for struct rte_eth_fdir_filter and
|
|
rte_eth_fdir_masks in order to support new flow director modes,
|
|
MAC VLAN and Cloud, on x550. The MAC VLAN mode means the MAC and
|
|
VLAN are monitored. The Cloud mode is for VxLAN and NVGRE, and
|
|
the tunnel type, TNI/VNI, inner MAC and inner VLAN are monitored.
|
|
The release 2.2 will contain these changes without backwards compatibility.
|
|
|
|
* librte_pmd_ring: The deprecated functions rte_eth_ring_pair_create and
|
|
rte_eth_ring_pair_attach should be removed.
|
|
|
|
* ABI changes are planned for struct virtio_net in order to support vhost-user
|
|
multiple queues feature.
|
|
It should be integrated in release 2.2 without backward compatibility.
|
|
|
|
* The scheduler hierarchy structure (rte_sched_port_hierarchy) will change to
|
|
allow for a larger number of subport entries.
|
|
The number of available traffic_classes and queues may also change.
|
|
The mbuf structure element for sched hierarchy will also change from a single
|
|
32 bit to a 64 bit structure.
|
|
|
|
* The scheduler statistics structure will change to allow keeping track of
|
|
RED actions.
|
|
|
|
* librte_cfgfile: In order to allow for longer names and values,
|
|
the value of macros CFG_NAME_LEN and CFG_NAME_VAL will be increased.
|
|
Most likely, the new values will be 64 and 256, respectively.
|
|
|
|
* librte_port: Macros to access the packet meta-data stored within the
|
|
packet buffer will be adjusted to cover the packet mbuf structure as well,
|
|
as currently they are able to access any packet buffer location except the
|
|
packet mbuf structure.
|
|
|
|
* librte_table LPM: A new parameter to hold the table name will be added to
|
|
the LPM table parameter structure.
|
|
|
|
* librte_table: New functions for table entry bulk add/delete will be added
|
|
to the table operations structure.
|
|
|
|
* librte_table hash: Key mask parameter will be added to the hash table
|
|
parameter structure for 8-byte key and 16-byte key extendible bucket and
|
|
LRU tables.
|
|
|
|
* librte_pipeline: The prototype for the pipeline input port, output port
|
|
and table action handlers will be updated:
|
|
the pipeline parameter will be added, the packets mask parameter will be
|
|
either removed (for input port action handler) or made input-only.
