[dpdk-dev] [PATCH v3 07/17] ethdev: export init/uninit common wrappers for pci drivers

[Shreyansh Jain]

From: David Marchand <david.march...@6wind.com>

Preparing for getting rid of eth_drv, here are two wrappers that can be
used by pci drivers that assume a 1 to 1 association between pci resource and
upper interface.
