Routed sub-interface naming convention

https://github.com/Azure/SONiC/pull/833

 

 

Linux kernel has a limitation of 15 character interface name size, modify the sub interface naming convention to keep it in short format (e.g. Eth100.1234, or Po100.1234). This naming change for subinterfaces will kept it uniform across the entire SONiC subsystem (config, show, and in all dbs) for the subinterfaces. DB migrator scripts are enhanced for the name conversion during the upgrade.

System Ready Enhancements

https://github.com/Azure/SONiC/pull/875/files

 

Today there is no easy way to know when the device is ready in terms of control/dataplane. The change allows declaration of System ready (Syslog/CLI) when all the services(dockers+host) are up and ready. Also define a framework for each service to declare itself ready based on their application criteria.
