HDMI TX Core Drops AVI and VSI Packets on the Auxiliary Data Port

When you use the HDMI TX core with the Support auxiliary parameter turned on, the IP core always drops the Auxiliary Video Infoframe (AVI) and Vendor Specific Infoframe (VSI) packets on the auxiliary data port (aux_data), regardless of the MSB of each auxiliary control port, info_avi[112] and info_vsi[61] respectively.

Do not use the auxiliary data port (aux_data) to carry the AVI and VSI packets. Instead, provide the intended AVI and VSI on each auxiliary control port (info_avi[111:0] and info_vsi[60:0]). The HDMI TX core will insert these packets from the control port into the auxiliary packet. You can set the MSB of each auxiliary port to 0 or 1.

This issue is fixed in version 15.1 of the HDMI IP core.
