This commit adds NTP support for management VRF using L3mdev. Config vrf add mgmt will enable management VRF, enslave the eth0 device to the master device mgmt, stop ntp service in default, restart interfaces-configs and restart ntp service in mgmt-vrf context. Requirement and design are covered in mgmt vrf design document. Signed-off-by: Harish Venkatraman <harish_venkatraman@dell.com>

# This file was originally created automatically as part of default NTP application installation from debian package.
|
|
# This is now manually modified for supporting NTP in management VRF.
|
|
# When management VRF is enabled, the NTP application should be started using "cgexec -g l3mdev:mgmt".
|
|
# Check has been added to verify the management VRF enabled status and use cgexec when it is enabled.
|
|
# This file will be copied on top of the etc/init.d/ntp file that gets created during build process.
