Problem

The README dedicates an entire section to DPDK as a platform integration option. The integration guide lists it as a "Reference" implementation. The comparison table recommends it for "Maximum performance" use cases. Yet no src/Magma.DPDK project exists.

This is the largest missing piece. Start with the foundation.

Sub-tasks

• Create src/Magma.DPDK project, add to solution
• P/Invoke bindings: rte_eal_init, rte_eth_dev_configure, rte_eth_dev_start
• rte_pktmbuf_pool_create for memory pool setup
• Huge page detection and configuration helpers
• EAL argument builder (core mask, memory channels, PCI allowlist)
• Docker image with DPDK 23.11+ for CI builds
• Compile-time check: only build on Linux

Dependencies

Depends on: #99 (CI), #113 (performance baseline for comparison)
Unlocks: #127 (DPDK single-queue RX/TX)

Phase

Phase 3 (Advanced Integrations)
