Subject: [dpdk-dev] [PATCH v5 2/4] net/iavf: support Ethernet CRC strip disable
Date: Mon, 11 Jan 2021 21:34:04 +0800
Message-ID: <20210111133406.484200-3-haiyue.wang@intel.com> (raw)
In-Reply-To: <20210111133406.484200-1-haiyue.wang@intel.com>

The VF will check the PF's CRC strip capability firstly, then set the
'CRC strip disable' value in the queue configuration according to the
RX CRC offload setting.
