Subject: [PATCH v4 1/3] net/iavf: support Tx LLDP on scalar
Date: Thu, 21 Dec 2023 15:28:25 +0800 [thread overview]
Message-ID: <20231221072827.1808983-2-zhichaox.zeng@intel.com> (raw)
In-Reply-To: <20231221072827.1808983-1-zhichaox.zeng@intel.com>
This patch adds an mbuf dynfield IAVF_TX_LLDP_DYNFIELD to determine
whether or not to fill the SWTCH_UPLINK bit in the Tx context descriptor
to send LLDP packet.
