Subject: [dpdk-dev] [PATCH v4 1/3] net/i40e: enable per dev PTYPE mapping table
Date: Thu, 30 Mar 2017 07:29:57 -0400	[thread overview]
Message-ID: <20170330112959.12477-2-qi.z.zhang@intel.com> (raw)
In-Reply-To: <20170330112959.12477-1-qi.z.zhang@intel.com>

The mapping from hardware defined packet type to software defined
packet type is static for i40e device, the patch let each ethdev to
to have their own copy of mapping table, this give the possibility
that different ethdev can be set different PTYPE mapping rule which
is the requirement to support following hardware's dynamic PTYPE
feature.
