Why do the DisplayPort design examples in Quartus II software versions 15.0 and 15.0.1 not work?

Description

The DisplayPort demo designs in Quartus® II versions 15.0 and 15.0.1 have incorrect signal connections at the top level. At bitec_reconfig_alt_av interface, tx_link_rate is connected to the Rx link rate control bits as shown below. 

  .tx_link_rate           (dp_rx_reconfig_link_rate_8bits)

Also, there are missing functions in the software.

Workaround/Fix

The issue is fixed in Quartus II software versions 15.0.2 and later.
