Subject: [dpdk-dev] [PATCH 2/8] net/iavf: set min and max MTU for VF
Date: Sun, 27 Sep 2020 07:26:20 +0000 [thread overview]
Message-ID: <20200927072626.28374-3-robinx.zhang@intel.com> (raw)
In-Reply-To: <20200927072626.28374-1-robinx.zhang@intel.com>
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.
