Configure the VFAT HDLC addresses when appropriate

Description

In new releases of the backend firmware, the HDLC addresses of the VFAT are configurable and default to 0. This prevents communication in systems that use the VFAT addressing.

The HDLC addresses must be configured after the backend firmware loading/registers reset.

Relevant logs and/or screenshots

All addresses default to 0 on a GE2/1 system after an FPGA programming:
