Subject: [dpdk-dev] [PATCH] doc: announce API and ABI change for ethdev
Date: Wed, 12 Jul 2017 15:58:46 +0800 [thread overview]
Message-ID: <20170712075846.14834-1-zhiyong.yang@intel.com> (raw)
This is an API/ABI change notice for DPDK 17.11 on redefinition of
port_id. port_id is defined as uint8_t by now, which is just ranged
from 0 to 255. For more and more scenerioes, more than 256 devices are
needed to support for vdev scalability.
It is necessary for redefinition of port_id to extend from 1 bytes
to 2 bytes. All ethdev APIs and use cases related to port_id will be
changed at the same time.

Target release for removal of the legacy API will be defined once most
PMDs have switched to rte_flow.
+* ABI/API changes are planned for 17.11 in the "rte_eth_dev_data" structure.
+ Change the definition of port_id from 8bits to 16bits in order to support
+ more than 256 devices in DPDK.

* librte_table: The ``key_mask`` parameter will be added to all the hash tables
that currently do not have it, as well as to the hash compute function prototype.
The non-"do-sig" versions of the hash tables will be removed
