Zerocopy benchmarks over dummy showed ~5% tx/s improvement, should be similar for small payload non-zc cases. The performance comes from killing 4 atomics and a couple of big struct memcpy/memset. 1/10 removes a pair of atomics on dst refcounting for cork->skb setup, 9/10 saves another pair on cork init. 5/10 and 8/10 kill extra 88B memset and memcpy respectively. ==================== Link: https://lore.kernel.org/r/cover.1643243772.git.asml.silence@gmail.com Signed-off-by: Jakub Kicinski --- e7d786331c62f260fa5174ff6dde788181f3bf6b
