Subject: [dpdk-dev] [PATCH v2] net/i40e: enable MAC address as FDIR input set
Date: Wed, 18 Mar 2020 03:15:06 +0000
Message-ID: <20200318031506.79773-1-lunyuanx.cui@intel.com> (raw)
In-Reply-To: <20200316004722.5323-1-lunyuanx.cui@intel.com>

FVL enable both src MAC address and dst MAC address as FDIR's input
set for ipv4-other. And FVL enable only dst MAC address as FDIR's
input set for ipv4-other. When OVS-DPDK is working as a pure L2 switch,
Both two ways match offload with Mark+RSS action would help the
performance speed up. And FVL FDIR supports to change input set as
both two ways.

v2:
 - Enable src MAC address as FDIR's input set
