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. cc: jianfeng....@intel.com cc: y...@fridaylinux.org cc: jerin.ja...@caviumnetworks.com cc: tho...@monjalon.net cc: remy.hor...@intel.com Signed-off-by: Zhiyong Yang <zhiyong.y...@intel.com> Acked-by: Jianfeng Tan <jianfeng....@intel.com> Acked-by: Yuanhan Liu <y...@fridaylinux.org> Acked-by: Jerin Jacob <jerin.ja...@caviumnetworks.com> Acked-by: Remy Horton <remy.hor...@intel.com> --- Change in V3. update the commit log.
