This lists are supposed to serve for storing pointers to all upper devices.
Eventually it will replace dev->master pointer which is used for
bonding, bridge, team but it cannot be used for vlan, macvlan where
there might be multiple "masters" present.

New upper device list resolves this limitation. Also, the information
stored in lists is used for preventing looping setups like
"bond->somethingelse->samebond"

Hi, Jiri,

I have some difficulty to understand this patch description, so take
bridged bonding as an example, IIUC, both the bridge dev and bonding
dev will be in the upper dev list of eth0 and eth1? And br0 will be
in the upper dev list of bond0 too?

No. Only direct upper device is in the list.

I think it would be nice to describe the hierarchy after your patches.

Hierarchy is the same after.

Thanks!
