[NET]: Expose netdevice dev_id through sysfs
Expose dev_id to userspace, because it helps to disambiguate between interfaces where the MAC address is unique. This should allow us to simplify the handling of persistent naming for S390 network devices in udev -- because it can depend on a simple attribute of the device like the other match criteria, rather than having a special case for SUBSYSTEMS=="ccwgroup".
