From f611dada1af8d32a0264c4b8c2066c8cdc12edb8 Mon Sep 17 00:00:00 2001 From: Jiawen Wu Date: Mon, 29 Mar 2021 11:17:21 +0800 Subject: [PATCH] net/txgbe: update link setup process of backplane NICs Add device arguments to support runtime options. And use these configuration to control the link setup flow, to adapt to different NIC's construction. Use firmware version to control the impact of firmware update. And fix some left bugs.
