So now there is possible to create ovs bridge over rocker switch ports. ovs daemon can decide which flows to offload to hw and uses switchdev genl api to tell driver. For now the easiest way it to do it by hand via "sw" tool (https://github.com/jpirko/switchdev). v1->v2 changes: - removed DSA phys switch id implementation for now per Florian's request - introduced own match key structure so the internal ovs flow struct stays untouched - extended the flow match in order to easily add more match types (hope that Jamal will like this :) - per ovs maintainers' request, removed ovs offload bits - that will be handled in ovs userspace using switchdev genl interface. - added switchdev features so that driver can indicate what it supports - little renames/fixes here and there RFC->v1 changes: - moved include/linux/*.h -> include/net/ - moved net/core/switchdev.c -> net/switchdev/ - moved drivers/net/rocker.* -> drivers/net/ethernet/rocker/ - fixed couple of little bugs and typos - in dsa the switch id is generated randomly - fixed rocker schedule in atomic context bug in rocker_port_set_rx_mode - added switchdev Netlink API Jiri Pirko (9): net: rename netdev_phys_port_id to more generic name net: introduce generic switch devices support rtnl: expose physical switch id for particular device net-sysfs: expose physical switch id for particular device net: introduce dummy switch switchdev: add basic support for flow matching and actions switchdev: add swdev features switchdev: introduce Netlink API rocker: introduce rocker switch driver Documentation/networking/switchdev.txt | 53 + MAINTAINERS | 14 + drivers/net/Kconfig | 7 + drivers/net/Makefile | 1 + drivers/net/dummyswitch.c | 130 + drivers/net/ethernet/Kconfig | 1 + drivers/net/ethernet/Makefile | 1 + drivers/net/ethernet/broadcom/bnx2x/bnx2x_main.c | 2 +- drivers/net/ethernet/intel/i40e/i40e_main.c | 2 +- drivers/net/ethernet/mellanox/mlx4/en_netdev.c | 2 +- drivers/net/ethernet/qlogic/qlcnic/qlcnic_main.c | 2 +- drivers/net/ethernet/rocker/Kconfig | 29 + drivers/net/ethernet/rocker/Makefile | 5 + drivers/net/ethernet/rocker/rocker.c | 3561 ++++++++++++++++++++++ drivers/net/ethernet/rocker/rocker.h | 465 +++ include/linux/netdevice.h | 49 +- include/net/switchdev.h | 160 + include/uapi/linux/if_link.h | 10 + include/uapi/linux/switchdev.h | 113 + net/Kconfig | 1 + net/Makefile | 3 + net/core/dev.c | 2 +- net/core/net-sysfs.c | 26 +- net/core/rtnetlink.c | 30 +- net/switchdev/Kconfig | 20 + net/switchdev/Makefile | 6 + net/switchdev/switchdev.c | 188 ++ net/switchdev/switchdev_netlink.c | 441 +++ 28 files changed, 5307 insertions(+), 17 deletions(-) create mode 100644 Documentation/networking/switchdev.txt create mode 100644 drivers/net/dummyswitch.c create mode 100644 drivers/net/ethernet/rocker/Kconfig create mode 100644 drivers/net/ethernet/rocker/Makefile create mode 100644 drivers/net/ethernet/rocker/rocker.c create mode 100644 drivers/net/ethernet/rocker/rocker.h create mode 100644 include/net/switchdev.h create mode 100644 include/uapi/linux/switchdev.h create mode 100644 net/switchdev/Kconfig create mode 100644 net/switchdev/Makefile create mode 100644 net/switchdev/switchdev.c create mode 100644 net/switchdev/switchdev_netlink.c -- 1.9.3 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
