From: Gagandeep Singh Date: Wed, 23 Oct 2019 06:06:02 +0000 (+0530) Subject: net/enetc: enable dpaax library X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e56463ec47f0;p=dpdk.git net/enetc: enable dpaax library dpaaX is used to maintain a local copy of PA->VA translations. Using the rte_mem_virt2iova or rte_mem_virt2phy is expensive. This library is an attempt to reduce the overall cost associated with this translation. This patch enables this dpaaX library by populating a dpaaX's table for PA to VA translation. This change will also help the caam JR driver in PA to VA translation when used with enetc driver over enetc supported SoCs.
