Subject: [PATCH net-next] net: ipconfig: allow IP-Config over DSA devices

Hi David, Lennert, Jiri,

This small patch allows us to use the kernel IP auto-configuration on DSA
enabled devices.

I initially started implementing the netdev_upper_dev_link() calls for the
DSA slave devices, but ended up realizing that although this might be useful,
the other drivers or protocols implementing these master/slave relantionship
are the bonding driver and the VLAN code.

None of these interfaces (bonding or VLAN) can be created by the kernel
without modifications, which means that user-space is there, and so we could
pivot_root over a NFS mounted share for instance, hence making the master/slave
net_device relationship not so useful for IP-Config.

This is not the case with DSA devices which are solely created by the kernel
based on platform configuration.

Let me know your thoughts. If you feel like something like:
netdev_is_upper_dev() or something like that is better.

Thanks!
