From: Andrey Vesnovaty Date: Fri, 23 Oct 2020 10:24:07 +0000 (+0300) Subject: common/mlx5: modify advanced Rx object via DevX X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=847d97894bcd2aacbc8934e3e12d90c39dd6266f;p=dpdk.git common/mlx5: modify advanced Rx object via DevX Implement TIR modification (see mlx5_devx_cmd_modify_tir()) using DevX API. TIR is the object containing the hashed table of Rx queue. The functionality to configure/modify this HW-related object is prerequisite to implement rete_flow_shared_action_update() for shared RSS action in mlx5 PMD. HW-related structures for TIR modification add in mlx5_prm.h.
