**- Why I did it** PR https://github.com/Azure/sonic-buildimage/pull/4599 introduced two bugs in the startup of the router advertiser container: 1. References to the `wait_for_intf.sh` script were changed to `wait_for_link.sh`, but the actual script was not renamed 2. The `ipv6_found` Jinja2 variable added to the supervisor config file goes out of scope before it is read. **- How I did it** 1. Rename the `wait_for_intf.sh` script to `wait_for_link.sh` 2. Use the Jinja2 "namespace" construct to fix the scope issue **- How to verify it** Ensure all processes in the radv container start properly under the correct conditions (i.e., whether or not there is at least one VLAN with an IPv6 address assigned).
