This series refactors this infrastructure to be NUMA aware, and lockless. Tested on various platforms, including AMD Zen 2/3/4 and Intel Granite Rapids, showing significant cost reductions under network stress (more than 20 Mpps). ==================== Link: https://patch.msgid.link/20250928084934.3266948-1-edumazet@google.com Signed-off-by: Paolo Abeni --- c18b0f5af42f8f98d4d629e578608188c0ce4652
