Subject: [dpdk-dev] [PATCH v1 3/6] net/i40e: set min and max MTU for i40e VF devices
Date: Wed, 27 Feb 2019 21:45:45 +0000 [thread overview]
Message-ID: <1551303948-19746-4-git-send-email-ian.stokes@intel.com> (raw)
In-Reply-To: <1551303948-19746-1-git-send-email-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.
