[ovs-dev] I think I found a bug

I expected that since the flow with the lower priority will never be 
matched over the higher one, it has no purpose and would not be added.

Hmm, on second glance, the protocol says that if you add an identical 
flow that also has the same priority then the flow will just be replaced.
But, I don't think it says anything about this case. Sorry, I should 
have confirmed that before posting.

That said, do you think these identical flows should be allowed?
