Hi James,

We gave up on enforcing the order a long time ago.

Vivek, if you want to submit a patch allowing duplicate IEs as long as they are 
bit-identical (length, and contents), I think that would be okay.  From what I 
can see our logic should be only picking up the first occurrence.

Regards,
-Denis
