* ZTP infrastructure changes to support DHCP discovery provisioning data - Dynamically generate DHCP client configuration based on current ZTP state - Added support to request and process hostname when using DHCPv6 - Do not process graphservice url dhcp option if ZTP is enabled, ZTP service will process it - Generate /e/n/i file with all active interfaces seeking address assignment via DHCP. Only interfaces that are created in Linux will be added to /e/n/i. Also DHCP is started only on linked up in-band interfaces. Signed-off-by: Rajendra Dendukuri <rajendra.dendukuri@broadcom.com>
