[dpdk-dev] [PATCH v2 5/6] drivers: refactor DPAA2 object definition

Shreyansh Jain shreyansh.jain at nxp.com
Fri Aug 25 12:19:53 CEST 2017


Initially, DPAA2 objects (except ETH and CRYPTO) were defined from VFIO
layer. This patch moves that into Bus definition.
This patch also realigns the object types with the new device types.
