The NetDIM library provides excellent acceleration for many modern network cards. However, the default profiles of DIM limits its maximum capabilities for different NICs, so providing a way which the NIC can be custom configured is necessary. Currently, interaction with the driver is still based on the commonly used "ethtool -C". Since the profile now exists in netdevice, adding a function similar to net_dim_get_rx_moderation_dev() with netdevice as argument is nice, but this would be better along with cleaning up the rest of the drivers, which we can get to very soon after this set. Please review, thank you very much! Changelog ===== v6->v7: - A new wrapper struct pointer is used in struct net_device. - Add IS_ENABLED(CONFIG_DIMLIB) to avoid compiler warnings. - Profile fields changed from u16 to u32. v5->v6: - Place the profile in netdevice to bypass the driver. The interaction code of ethtool <-> kernel has not changed at all, only the interaction part of kernel <-> driver has changed. v4->v5: - Update some snippets from Kuba, Thanks. v3->v4: - Some tiny updates and patch 1 only add a new comment. v2->v3: - Break up the attributes to avoid the use of raw c structs. - Use per-device profile instead of global profile in the driver. v1->v2: - Use ethtool tool instead of net-sysfs Heng Qi (4): linux/dim: move useful macros to .h file ethtool: provide customized dim profile management virtio-net: refactor dim initialization/destruction virtio-net: support dim profile fine-tuning Documentation/netlink/specs/ethtool.yaml | 33 +++ Documentation/networking/ethtool-netlink.rst | 8 + drivers/net/virtio_net.c | 46 +++-- include/linux/dim.h | 13 ++ include/linux/ethtool.h | 11 +- include/linux/netdevice.h | 24 +++ include/uapi/linux/ethtool_netlink.h | 24 +++ lib/dim/net_dim.c | 10 +- net/core/dev.c | 83 ++++++++ net/ethtool/coalesce.c | 199 ++++++++++++++++++- 10 files changed, 428 insertions(+), 23 deletions(-)
