This just empowers fieldbus devices to id themselves as 'flnet' when they
register with the core:
priv->fbdev.fieldbus_type = FIELDBUS_DEV_TYPE_FLNET;
...
err = fieldbus_dev_register(&priv->fbdev);
The core exports this as a sysfs property, so that userspace has a
standardized way of determining the fieldbus type when looking at the
fieldbus dev's sysfs dir.
Yes the commit message is too confusing. I'll write a better one if/when I
repost flnet support. Might be a while because you indicated "no new h/w
support while still in staging".
