For as far as I know, ip link is able to enslave and to detach a slave, but not to change the active 
slave. So I think you cannot mimic the -c|--change-active option of ifenslave just using iproute. Do 
I miss something?

That being said, I'm not sure this particular option is the most used one, but...
