LINUX: ifconfig is deprecated

Browse Source 
ifconfig is deprecated and is no longer installed by default on RHEL 7 and
Centos 7. Use the replacement ip command in the init script for linux.
Fallback to ifconfig in the event the ip command is not available.

Thanks to Ben Kaduk for pointing out the hash built-in command.
