From e69d36c549609c02b6814cd06232e340fe0b873b Mon Sep 17 00:00:00 2001
From: Leyi Rong <leyi.rong@intel.com>
Date: Wed, 8 Apr 2020 14:22:05 +0800
Subject: [DPDK 11/17] 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.
