From ee4e4040ab6191f9431afad9a2deec76f6759cad Mon Sep 17 00:00:00 2001 From: "Shiraz, Saleem" Date: Wed, 25 Sep 2019 11:45:24 -0500 Subject: RDMA/i40iw: Associate ibdev to netdev before IB device registration i40iw IB device registration fails with ENODEV. ib_register_device setup_device/setup_port_data i40iw_port_immutable ib_query_port iw_query_port ib_device_get_netdev(ENODEV) ib_device_get_netdev() does not have a netdev associated with the ibdev and thus fails. Use ib_device_set_netdev() to associate netdev to ibdev in i40iw before IB device registration.
