That is what the patch does.

I don't quite follow what you're asking here.  Local QPNs are tracked when a REQ 
is sent.  If a second REQ is sent using the same QPN, it will fail with an 
address in use error.  The local QPN is not removed from the table until the 
connection fails, or we exit the timewait state after being disconnected.
