Conversation
Summary of ChangesHello @LAVEEN, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly upgrades the networking infrastructure by integrating advanced IPv6 features and introducing support for a new high-performance network interface card type, IDPF. These changes aim to provide more robust, scalable, and specialized networking options, particularly for high-performance computing environments, while also refining the configuration logic for specific network profiles.

Code Review
This pull request adds support for IPv6 and the IDPF NIC type. The changes primarily involve updating Terraform variable definitions, validation logic, and passing new parameters to underlying modules. My review has identified a high-severity bug in modules/network/gpu-rdma-vpc/main.tf that could lead to a Terraform error when using a vpc-roce-metal profile due to unsafe attribute access on a potentially null variable. I have provided a code suggestion to fix this. Additionally, I've included several medium-severity suggestions to improve code readability, maintainability, and style consistency across the modified files, such as simplifying validation logic and correcting formatting in variable descriptions.

Code Review
This pull request introduces significant networking enhancements, including IPv6 support, IDPF interface support, and improved handling for RoCE metal network profiles. The changes are well-structured and align with the project's goals. The addition of IPv6 ULA options in the vpc module and IDPF nic type in vm-instance are correctly implemented. The logic to handle vpc-roce-metal profiles in the gpu-rdma-vpc module, where subnetwork creation is skipped, is a thoughtful addition. I've left a couple of minor suggestions to improve the formatting of error messages for better consistency.

There are a couple of minor formatting issues in this error message. There's a missing space after the comma before "IDPF", and two spaces after it. For consistency and improved readability, please ensure there is a single space after each comma in the list.
error_message = "In the variable network_interfaces, field \"nic_type\" must be \"GVNIC\", \"VIRTIO_NET\", \"MRDMA\", \"IRDMA\", \"IDPF\" or null."

There's a minor formatting issue here. A space has been added before the comma, which is inconsistent with standard punctuation. Please remove the space before the comma for consistency.
error_message = "In the variable network_interfaces, field \"stack_type\" must be either \"IPV4_ONLY\", \"IPV4_IPV6\", \"IPV6_ONLY\" or null."

This Pull Request significantly enhances the networking capabilities of the Cluster Toolkit by integrating comprehensive IPv6 support, adding Intel Intelligent Data Processing Unit (IDPF) interface support, and refining the handling of specialized bare metal network profiles. These updates ensure the toolkit can provision the high-performance networking infrastructure required for modern, large-scale compute environments.
