For more and more scenerioes, more than 256 ports 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. cc: jianfeng.tan@intel.com cc: yliu@fridaylinux.org cc: jerin.jacob@caviumnetworks.com cc: thomas@monjalon.net Signed-off-by: Zhiyong Yang <zhiyong.yang@intel.com> Acked-by: Jianfeng Tan <jianfeng.tan@intel.com> Acked-by: Yuanhan Liu <yliu@fridaylinux.org> Acked-by: Jerin Jacob <jerin.jacob@caviumnetworks.com> --- Change in V2. 1. remove indent of paragraph in commit log. 2. add more description about API/ABI according to yuanhan's comments. doc/guides/rel_notes/deprecation.rst | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/doc/guides/rel_notes/deprecation.rst b/doc/guides/rel_notes/deprecation.rst index 72aa40495..4edaf92fb 100644 --- a/doc/guides/rel_notes/deprecation.rst +++ b/doc/guides/rel_notes/deprecation.rst @@ -49,6 +49,12 @@ Deprecation Notices 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.
