Subject: [dpdk-dev] [PATCH v2] net/ice: set min and max MTU
Date: Tue, 7 May 2019 09:53:46 +0800 [thread overview]
Message-ID: <20190507015346.32214-1-qi.z.zhang@intel.com> (raw)
This commit sets the min and max supported MTU values for ice devices
via the ice_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.
