Subject: [dpdk-dev] [PATCH v2 7/7] app/testpmd: verify mtu with rte_eth_dev_info_get()
Date: Fri, 22 Mar 2019 13:01:18 +0000	[thread overview]
Message-ID: <1553259678-4515-8-git-send-email-ian.stokes@intel.com> (raw)

In-Reply-To: <1553259678-4515-1-git-send-email-ian.stokes@intel.com>

This commit uses the mtu fields populated in rte_eth_dev_info_get()
to validate the mtu value being passed in port_mtu_set().
