Self-NAK on this version, there is a bug - desynchronization of
adj_list/all_adj_list lists in case we make a loop consecutively (otherwise
it won't trigger):

ifenslave bond0 eth0
vconfig add eth0 100
ifenslave bond0 eth0.100
ifesnlave -d bond0 eth0.100

It's, however, easily fixable (and quite a rare scenario) - so all reviews
are still welcome. I'll continue testing and waiting for any input.

Thanks all!
