From: Bing Zhao Date: Wed, 5 May 2021 12:23:12 +0000 (+0300) Subject: common/mlx5: add connection tracking object X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=dc4e9e820f2d0d2d32b0a34cdec3b27515c8f002;p=dpdk.git common/mlx5: add connection tracking object The structures of ASO connection tracking offload object are added based on the definitions in the PRM. One CT object context will be loaded into the cache completely in a reversed order of dwords. The valid bit should be the MSB of the last dword. This is used for the conntrack context creation and update, as well as for the query. The capabilities 2 (HCA_CAP_2) layout is also added. The connection tracking related capabilities could be queried via the HCA_CAP_2.
