Using can_intersect() is not needed when you start considering upstream caps
during negotiation and re-negotiation. But I'm not done with that, as I am
facing some race conditions, this is the reason the patch set was not merged. I
think the patch 229286 is the only patch that may be be used by alone, but need
testing. I'll try to finish this work by the end of march, but it's a difficult
problem to do N to 1 negotiation. We have similar issues with adder and
liveadder elements.
