mlx5-updates-2019-01-25
This series provides some updates to mlx5 driver, From Tariq, 1) Make sure RX packet header does not cross page boundary To avoid page boundary crossing, use stride size that fits the maximum possible header. Stride is increased form 64B to 256B. 2) CQ struct cleanup: Take CQ decompress fields into a separate structure From Moshe, 3) Expand XPS cpumask to cover all online cpus From Jason Gunthorpe and Tariq: 4) Compilation warning cleanup From Or, 5) Add trace points for flow tables create/destroy From Saeed, 6) Software stats update/folding improvements this also solves a compilation warning on 32bit systems that was reported last release cycle by Arnd and Andrew. Thanks, Saeed. -----BEGIN PGP SIGNATURE----- iQEcBAABAgAGBQJcS26PAAoJEEg/ir3gV/o+mE8IAIa5IAl67N2W3arrpfpgImFU ld1qbmnKXYHaapfPHJRVM1hKoA+1nsSOzPgTd7WliPZ+Bjk+SeQ/XW2oMnK995am m3EQb+8jxAWFnvzwW8pdWeE/gYsR1pA5FzIm3bBpzpSww/rPLUsLUpVYlm7uIo3L r4XJPE8ALQvg2SM6MxFWqGVEpKr9FNaXBEjiWnelcoxjTLKyawt5T96dUn7lxDw1 6VC+eYEhkvkg+wfWKNFxyrT3u97KyVcvup25zsA/+aiNeRbeqE9GtTKe9JqXTcxw 3I8yhxhSaudSe0LZ3MDWIVrMeWFgiVoq9r7lkmYDdkAP+FWcRuEHQQKqz0PvxZI= =+Kz6 -----END PGP SIGNATURE----- Merge tag 'mlx5-updates-2019-01-25' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2019-01-25 This series provides some updates to mlx5 driver, From Tariq, 1) Make sure RX packet header does not cross page boundary To avoid page boundary crossing, use stride size that fits the maximum possible header.
