From 719469f13b11dbdc921b74258f2d10bd1c5328d4 Mon Sep 17 00:00:00 2001 From: Jie Wang Date: Thu, 10 Nov 2022 11:45:24 +0800 Subject: [PATCH] net/i40e: fix jumbo frame Rx with X722 For NIC I40E_10G-10G_BASE_T_X722, when the port is configured with link speed, it cannot receive jumbo frame packets. Because it set maximum frame size failed when starts the port that the port link status is still down. This patch fix the error that starts the port will force set maximum frame size.
