[dpdk-dev] [PATCH v12 3/4] bus/vdev: move to vdev bus to drivers/bus

Jianfeng Tan jianfeng.tan at intel.com
Tue Nov 7 07:54:21 CET 2017


Move the vdev bus from lib/librte_eal to drivers/bus.

As the crypto vdev helper function refers to data structure
in rte_vdev.h, so we move those helper function into drivers/bus
too.
