I'd propose to extend the netlink configuration interface, f.e. introduce a
new netlink attribtue IFLA_SLOT which can be provided to select the device
to be changed based on the slot number instead of the name/ifindex. That
would also make it trivial to write a small app using RTM_GETLINK to
translate a slot number to the corresponding interface name.
