This patchset fixes an invalid reference to mdev in mlx4 shutdown flow. In patch 1, we make sure netif_device_detach() is called from shutdown flow only, since we want to keep it present during a simple configuration change.
In patches 2 and 3, we add checks that were missing in: * dev_get_phys_port_id * dev_get_phys_port_name We check the presence of the network device before calling the driver's callbacks. This already exists for all other ndo's. Series generated against net commit: e5f6f564fd19 bnxt: add a missing rcu synchronization Thanks, Tariq.
