Subject: [dpdk-dev] [PATCH v3 3/7] net/i40e: set min and max MTU for i40e VF devices
Date: Fri, 29 Mar 2019 17:52:15 +0000	[thread overview]
Message-ID: <20190329175219.23831-3-ferruh.yigit@intel.com> (raw)
In-Reply-To: <20190329175219.23831-1-ferruh.yigit@intel.com>

From: Ian Stokes <ian.stokes@intel.com>

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.
