  "message": "net/mlx4_en: Saving mem access on data path\n\nLocalized the pdev-\u003edev, and using dma_map instead of pci_map\nThere are multiple map/unmap operations on data path,\noptimizing those by saving redundant pointer access.\nThose places were identified as hot-spots when running kernel profiling\nduring some benchmarks.\nThe fixes had most impact when testing packet rate with small packets,\nreducing several % from CPU load, and in some case being the difference\nbetween reaching wire speed or being CPU bound.\n\nSigned-off-by: Yevgeny Petrilin \u003cyevgenyp@mellanox.co.il\u003e\nSigned-off-by: David S.
