Hi Thomas, Sorry, I implemented it but was unsure that my test coverage was ideal a= s I was unable to access my usual switchable NaN hardware (FPGA based on interAp= tiv MR3) for testing. Will post patch after gain access to that again. Hardware ETA 10 Sept. Thanks - Jiaxun > > Thomas. > > --=20 > Crap can work.
