The first seven patches from Or Gerlitz in this series further enhances the mlx5 SRIOV switchdev mode to support offloading IPv6 tunnels using the TC tunnel key set (encap) and unset (decap) actions. Or Gerlitz says: ======================== As part of doing this change, few cleanups are done in the IPv4 code, later we move to use the full tunnel key info provided to the driver as the key for our internal hashing which is used to identify cases where the same tunnel is used for encapsulating multiple flows. As done in the IPv4 case, the control path for offloading IPv6 tunnels uses route/neigh lookups and construction of the IPv6 tunnel headers on the encap path and matching on the outer hears in the decap path. The last patch of the series enlarges the HW FDB size for the switchdev mode, so it has now room to contain offloaded flows as many as min(max number of HW flow counters supported, max HW table size supported). ======================== Next to Or's series you can find several patches handling several topics. From Mohamad, add support for SRIOV VF min rate guarantee by using the TSAR BW share weights mechanism. From Or, Two patches to enable Eth VFs to query their min-inline value for user-space. for that we move a mlx5 low level min inline helper function from mlx5 ethernet driver into the core driver and then use it in mlx5_ib to expose the inline mode to rdma applications through libmlx5. From Kamal Heib, Reduce memory consumption on kdump kernel. From Shaker Daibes, code reuse in CQE compression control logic Thanks, Saeed. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJYh7FNAAoJEEg/ir3gV/o+TjsIAL1e92+5eutBS9ZvhMARi+Tc c2V9V8bG8W1RWWTvx1G0aU4nNjWsr5L8Q8gzqpwhrQITBfgpWd+hlnxQCucyhxC3 AC1qQ+AKREe/C+25D+WJRq34/61ZHEH2rbKZvpZ1O8SuicVPbcvJ9eM+wOEDxwwX u5C5kWQ0HRtCcnFiiOYkB+0CQPH7m3+ZzZek+jDowrexHMSE+yl8ZNtaSTX9c9QN bE2cPiCVZd7ufKPIwY8LWHBryyl7sh5P+NqzD633OeiqP/pkZsW9A+czyt+d330f 6XTKOS1PCD+TfHE0sZJT4VMCjICMHrOFbNRZuwcxJQ6NfmwIJZfskX4NLbyGQTI= =vF7U -----END PGP SIGNATURE----- Merge tag 'mlx5-updates-2017-01-24' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2017-24-01 The first seven patches from Or Gerlitz in this series further enhances the mlx5 SRIOV switchdev mode to support offloading IPv6 tunnels using the TC tunnel key set (encap) and unset (decap) actions.
