From: Xiaolong Ye Date: Mon, 13 Jan 2020 02:39:18 +0000 (+0800) Subject: net/i40e/base: support LLDP agent X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=3c537ca7f403262f5ef64390af6d9f1234d46b31;p=dpdk.git net/i40e/base: support LLDP agent This code implements changes necessary for LLDP Agent support. 1. Modified i40e_aq_start_lldp and i40e_aq_stop_lldp. Now Stop and Start can also be persistent across power cycles. 2. Added new function i40e_aq_restore_lldp which restores factory setting for LLDP Agent or gets its status.
