RDMA/ipoib: Allow user space differentiate between valid dev_port
Systemd triggers the following warning during IPoIB device load:
mlx5_core 0000:00:0c.0 ib0: "systemd-udevd" wants to know my dev_id.
Should it look at dev_port instead?
See Documentation/ABI/testing/sysfs-class-net for more info.
This is caused due to user space attempt to differentiate old systems
without dev_port and new systems with dev_port. In case dev_port will be
zero, the systemd will try to read dev_id instead.
There is no need to print a warning in such case, because it is valid
situation and it is needed to ensure systemd compatibility with old
kernels.
