From 92645b2ffd842a14c461376c1dca199121396cc5 Mon Sep 17 00:00:00 2001 From: Ian Stokes Date: Fri, 29 Mar 2019 17:52:15 +0000 Subject: [PATCH] net/i40e: set min and max MTU for VF This commit sets the min and max supported MTU values for i40e VF devices via the i40evf_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.
