Detecting ethernet gadget connections

[Vasco Névoa]

I opened a ticket on that a while ago...
https://docs.openmoko.org/trac/ticket/2178
No progress in 3 months...

Citando Daniel Benoy <daniel at benoy.name>:

> I'm working on a script that will detect which network interfaces  
> are connected and mess with the routing accordingly, but I'm having  
> trouble detecting whether my USB ethernet gadget connection is up or  
> down.

> ethtool when it's up:
> lisa:~# ethtool usb0
> Settings for usb0:
> 	Link detected: yes
>
> ethtool when it's down:
> lisa:~# ethtool usb0
> Settings for usb0:
> 	Link detected: yes
> ----
>
> Unlike on the host side, the usb0 interface doesn't appear and  
> disappear, allowing udev scripts to bring up/down the interface.

> Anyone know if there's a way to detect that a network connection has  
> actually been established?
