Subject: dummy ethernet devices and sysfs

Hi,

I was looking through sysfs today, and something interesting jumped
out at me after I loaded the dummy module.

This directory exists: /sys/class/net/wlp2s0/device/

This directory does not: /sys/class/net/dummy0/device/

I can find the module that is providing the wlp2s0 device with the following:
$ ls /sys/class/net/wlp2s0/device/driver/module/drivers/
pci:iwlwifi

Shouldn't dummy have something similar so that one can figure out
which module is providing the dummy0 device?

FWIW, I am running the latest Ubuntu 15.10 kernel (4.2.0-23-generic).

Thanks,
wt
