Summary of Changes

Hello, 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 introduces documentation and test plans for validating sFlow sampling functionality in scenarios involving packet encapsulation and decapsulation. It ensures that sFlow samples correctly capture ingress/egress interfaces and packet headers across different tunneling protocols, providing a structured approach for future test implementation.

Highlights

• New sFlow Test Suite: Added comprehensive test documentation for sFlow sampling with various encapsulation and decapsulation scenarios, including GRE, GUE, and gRIBI-programmed encapsulation.
• Documentation Updates: Updated existing encapsulation test README files to include sFlow validation requirements and OpenConfig path coverage.
• Test Registry Update: Registered the new SFLOW-2 test plan in the global test registry.

Code Review

This pull request adds test plans and documentation for sFlow sampling with encapsulation and decapsulation. Specifically, it adds sFlow sampling test cases for IPv4/IPv6 WCMP encapsulation and decapsulation to the gRIBI basic encapsulation test plan, creates a new test plan (SFLOW-2) covering sFlow sampling with GRE, GUE, and gRIBI encapsulation/decapsulation, and adds sFlow sampling test cases for GUE encapsulated traffic to the static next-hop encapsulation UDP test plan. The reviewer feedback highlights a markdown header level inconsistency in the gRIBI test plan and a placeholder value left in the required DUT platform field of the new SFLOW-2 test plan.
