From f71dbf852d467b6684408b2957acf6a124ec2c32 Mon Sep 17 00:00:00 2001 From: Leyi Rong Date: Mon, 20 Apr 2020 14:16:20 +0800 Subject: [PATCH] net/iavf: add flow director enabled switch value The commit adds fdir_enabled flag into iavf_rx_queue structure to identify if fdir id is active. Rx data path can be benefit if fdir id parsing is not needed, especially in vector path.
