Subject: bus/vdev: add helper to get vdev from ethdev
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=2d9b1272609a408741673d1639dfef6c510f387f;p=dpdk.git

bus/vdev: add helper to get vdev from ethdev

This patch adds an helper macro to get the rte_vdev_device
pointer from a rte_eth_dev pointer.

This is similar to RTE_ETH_DEV_TO_PCI().
