From: Simei Su Date: Tue, 15 Oct 2019 15:09:47 +0000 (+0800) Subject: ethdev: decouple flow types and RSS offload types X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=fce6b66893d5f962f12c565ec6735ac8328f06ab;p=dpdk.git ethdev: decouple flow types and RSS offload types This patch decouples RTE_ETH_FLOW_* and ETH_RSS_*. The former defines flow types and the latter defines RSS offload types.
