Why I did it
Previously, if the SRv6 manager received a config update that added a SRV6_MY_SID entry before its corresponding LOCATOR entry added, the SRv6 manager would not process the SRV6_MY_SID entry and print an ERR syslog. However, during testing, NVIDIA team found that it is possible to have such a scenario in normal operations, especially during config reload. So, we decide to add a dependency-based caching mechanism to handle out-of-order table processing.
