From: Ian Stokes Date: Fri, 29 Mar 2019 17:52:14 +0000 (+0000) Subject: net/i40e: set min and max MTU X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c00deca2db34daa2d6ae335236507780db01f076;p=dpdk.git 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.
