Subject: [dpdk-dev] [PATCH] net/ice: set min and max MTU
Date: Sat,  4 May 2019 17:45:45 +0800	[thread overview]
Message-ID: <20190504094545.6039-1-qi.z.zhang@intel.com> (raw)
Message-ID: <20190504094545.b7faP8MzJy7T8vc_FRtF-jib9leNMwjFlPAg_zyrM70@z> (raw)

This commit sets the min and max supported MTU values for ice 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.
