RDMA/device: Add ib_device_get_by_netdev()
Several drivers need to find the ib_device from a given netdev. rxe needs this at speed in an unsleepable context, so choose to implement the translation using a RCU safe hash table. The hash table can have a many to one mapping. This is intended to support some future case where multiple IB drivers (ie iWarp and RoCE) connect to the same netdevs. driver_ids will need to be different to support this. In the process this makes the struct ib_device and ib_port_data RCU safe by deferring their kfrees. Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
