Enhance network boot provisioning with support for extra LAN IPs and VLAN configuration</message>

Browse Source 
<message>Update documentation and scripts to include configuration for extra LAN IPs on eth1 and VLAN interface eth1.40, allowing the LXC to serve multiple subnets and provide NAT for internet access. Modify nftables NAT configuration to accommodate these changes and ensure proper DHCP and DNS setup on eth1. This improves the overall network boot functionality and user experience for the CM4 eMMC provisioning service.
