While getting the ROACH2 core_info.tab parameters correct for the ADC16 yellow 
block, I noticed that core_info.tab is setup to specify the same starting 
offset of 60000 (hex) for both "sfp_gpio_data_in" and "qdr3_ctrl".  I built a 
test model consisting of QDR3 and an SFP+ core, but the only thing I saw in the 
system.mhs at address 0x60000 was sfp+ related.  The "qdr3_controller" instance 
didn't even have a base address.

It seems like maybe the "qdrX_ctrl" lines in the ROACH2 core_info.tab are 
extraneous and should be removed.  Can anyone familiar with the inner workings 
of the QDR block please comment?

Thanks,
Dave
