[docker-orchagent]: Add NDP Proxy Daemon (#5517) * Install ndppd during image build, and copy config files to image * Configure proxy settings based on config DB at container start * Pipe ndppd output to logger inside container to log output in syslog 2020-10-05 10:48:13 -05:00			`[program:ndppd]`
[swss]: Start ndppd after vlanmgrd (#9155) Why I did it During swss container startup, if ndppd starts up before/with vlanmgrd, ndppd will be pinned at nearly 100% CPU usage. How I did it Only start ndppd after vlanmgrd is running. Also, call ndppd directly instead of through bash for improved logging and to prevent orphaned processes.

[swss]: Wait for vlan intf to start ndppd (#10119) (#10153) 202012 version of #10119 Why I did it If the VLAN interface is not up when ndppd starts, it will fail to enable allmulti mode on the interface and be unable to process received NDP packets The following logs are seen: /var/log/syslog.33.gz:Feb 18 10:33:12.825406 sonic INFO swss#/supervisord: ndppd (error) Failed to set allmulti: No such device How I did it Use the wait_for_link script currently used by radv to delay ndppd startup until the vlan interface is ready How to verify it Apply the changes to a device. config reload the device and confirm that the above error logs are not observed when ndppd starts. Run the arp/test_arp_dualtor.py::test_proxy_arp test case and verify it passes. 2022-03-04 22:40:29 -06:00			`dependent_startup_wait_for=wait_for_link:exited`
