[for-next 06/12] IB/ipoib: Add ability to set PKEY index to lower device driver

[Saeed Mahameed]

From: Alex Vesker <va...@mellanox.com>

To support passing child interfaces to the lower device a new
rdma_netdev function was used, set_id. This will allow us to
attach the PKEY index lower device resources such as TIS/QP.
For devices that do not support offloads in IPoIB same logic
will be used, setting the PKEY index to priv struct.
