Subject: [PATCH net 0/3] mlx4 fix for shutdown flow

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.
