[dpdk-dev] [PATCH v3] net/mlx5: support new global device syntax

[Xueming Li <xuemingl@nvidia.com>]

This patch support new global device syntax like:
	bus=pci,addr=BB:DD.F/class=eth/driver=mlx5,devargs,..

In driver parameters check, ignores "driver" key which is part of new
global device syntax instead of reporting error.
