Summary of Changes
Hello @zbb88888, 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 addresses a bug by making the Vpc field optional for VLAN subnets within Kube-OVN. Previously, if the Vpc field was left empty for an OVN subnet, it would automatically default to the cluster router. This change introduces a refinement to ensure that for VLAN subnets, the Vpc field remains empty if not explicitly specified, which aligns with better security practices and provides more flexibility in configuration.
Highlights
- VLAN Subnet VPC Handling: Modified the
formatSubnetfunction inpkg/controller/subnet.goto ensure that for VLAN subnets, theVpcfield is not automatically set to the cluster router if it's initially empty. Instead, it will only default to the cluster router if bothVpcandVlanfields are empty.

Code Review
This pull request makes the VPC optional for VLAN subnets. The change correctly modifies the logic to avoid assigning a default VPC to VLAN subnets that don't have one specified. My review includes a suggestion to refactor the conditional logic for better readability and maintainability.

What type of this PR
Examples of user facing changes:
在 vlan subnet vpc 场景中，如果没有指定默认 vpc，而代码默认设置为 ovn-cluster，可能会导致一些安全上的问题。比如从 node 或者 默认 vpc 下的pod，可能可以访问 vlan 中的资源，尽管物理网络设计上是隔离的。
而且，如果用户愿意联通，则可以明确指定和哪个 vpc 联通。
