From 1541a9d6b07ac6c5b44f2f346223b24d25e1fc2f Mon Sep 17 00:00:00 2001 From: Robin Zhang Date: Sun, 27 Sep 2020 07:26:20 +0000 Subject: [PATCH] net/iavf: set min and max MTU for VF This commit sets the min and max supported MTU values for iavf VF devices via the iavf_dev_info_get() function. Min MTU supported is set to RTE_ETHER_MIN_MTU and max MTU is calculated as the max packet length supported minus the transport overhead.
