wait_for_sysfs warning in my driver

wait_for_sysfs warning in my driver

[ttabi2]

I have an ethernet driver that generates this warning on Fedora Core 3:

Dec  7 12:52:49 vic7 wait_for_sysfs[4254]: either wait_for_sysfs (udev 
039) needs an update to handle the device '/class/net/ccilnet0' properly 
(no device symlink) or the sysfs-support of your device's driver needs 
to be fixed, please report to <linux-hotplug-devel@lists.sourceforge.net>

I've been going through the archives of this mailing list, and I see a 
couple posts that suggest this is just a bug in udev, and not in my 
driver.  Is that correct?  If not, can someone give me a quick run-down 
as to what I need to do to update my driver?  I'm assuming this warning 
is because I'm using some deprecated interface.

It's not really a bug. If the device is backed by a physical device, it
should create the symlinks. Only virtual interfaces will not need to do
that.

Most networkd drivers use:
  SET_NETDEV_DEV(dev, &pdev->dev);

to create the expected links in sysfs. You may look at one of the
existing drivers how to do that in your driver.
