From c00deca2db34daa2d6ae335236507780db01f076 Mon Sep 17 00:00:00 2001 From: Ian Stokes Date: Fri, 29 Mar 2019 17:52:14 +0000 Subject: [PATCH] net/i40e: set min and max MTU This commit sets the min and max supported MTU values for i40e devices via the i40e_dev_info_get() function. Min MTU supported is set to ETHER_MIN_MTU and max mtu is calculated as the max packet length supported minus the transport overhead.
