Tool/software:

Hello team

I have a question about DP83867IR IBIS model

In the following E2E forum,  "Please change it to input and use it." was advised.
 https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1540908/dp83867ir-ibis-model-verification 

There are 2 kinds of input,  GPI  and  GPIO_SGMII_IN. Which should I select for 52pin?
