Subject: [dpdk-dev] [PATCH v3] doc: announce API and ABI change for ethdev
Date: Mon, 7 Aug 2017 20:42:30 +0800 [thread overview]
Message-ID: <20170807124230.3030-1-zhiyong.yang@intel.com> (raw)
In-Reply-To: <20170804052753.35535-1-zhiyong.yang@intel.com>
This is an API/ABI change notice for DPDK 17.11 announcing the redefinition
of port_id. port_id is currently defined as uint8_t, which is limited to
the range 0 to 255. A larger range is required for vdev scalability.
It is necessary for a redefinition of port_id to extend it from 1 bytes to
2 bytes. All ethdev APIs and usages 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 all structures which include port_id
+ definition such as "rte_eth_dev_data", "rte_port_ethdev_reader_params",
+ "rte_port_ethdev_writer_params", and so on. The definition of port_id will be
+ changed from 8 bits to 16 bits in order to support more than 256 ports in
+ DPDK. All APIs which have port_id parameter will be changed at the same time.
+
* 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
