From: Matan Azrad Date: Mon, 29 Jul 2019 11:53:28 +0000 (+0000) Subject: net/mlx5: allow implicit LRO flow X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5158260917a0588052500af4e011b6cd77143c1c;p=dpdk.git net/mlx5: allow implicit LRO flow When a user configures LRO in the port offloads, he probably wants each TCP packet will have a chance to open an LRO session. The PMD wasn't configure LRO in the flow TIR if the flow is not explicitly configured TCP item despite the flow included TCP traffic. For example, the next flows were not LRO offloaded: pattern eth / end, pattern eth / ip / end, pattern eth / ipv6 / end. Enable LRO configuration for all the TIRs if LRO is configured in the port. No performance impact for non-LRO traffic in these TIRs.
