Subject: [dpdk-dev] [RFC 2/6] net/i40e: set min and max MTU for i40e devices
Date: Wed, 20 Feb 2019 15:57:51 +0000 [thread overview]
Message-ID: <1550678275-4959-3-git-send-email-ian.stokes@intel.com> (raw)
In-Reply-To: <1550678275-4959-1-git-send-email-ian.stokes@intel.com>
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.
