Hi there, I'm not 100% certain about this patch but trial and error seems to confirm that this patch makes it indeed possible to use UNIQUE_KEY which I was not able to do with the current implementation. I would appreciate if somebody with access to this hardware could test this independently, e.g. the folks at sigma star who authored the original patch (3d16af0b4cfac).
