Automatically enables nvfp4 dispatch when the model uses nvfp4 quantization with DeepEP v2. Quantizes activations to nvfp4 with fp8 scale factors before dispatch for bandwidth reduction, and skips receiver-side requantization since data arrives kernel-ready. Extracted from elvircrn/vllm@deepep-v2-713b28bd (commits 63b6151 through 65778f1). Co-Authored-By: Claude Sonnet 4 <noreply@anthropic.com>
