KCU1500 I2C lock up into error state if there is a I2C read or write and no device connected at the time

      If the QSFP is not in the cage and you try to do a read or write, you get an error response in software.

       

      But if you plug that QSFP back into the cage, it never recovers from this error state until you do a power cycle or a reboot of the machine.

       

      I suspect this is a bug in our FW with respect to the I2C MUX on the KCU1500
