This patchset is just the first phase of switch and switch-ish device support api in kernel. Note that the api will extend. So what this patchset includes: - introduce switchdev api skeleton for implementing switch drivers - introduce rocker switch driver which implements switchdev api fdb and bridge set/get link ndos As to the discussion if there is need to have specific class of device representing the switch itself, so far we found no need to introduce that. But we are generally ok with the idea and when the time comes and it will be needed, it can be easily introduced without any disturbance. This patchset introduces switch id export through rtnetlink and sysfs, which is similar to what we have for port id in SR-IOV. I will send iproute2 patchset for showing the switch id for port netdevs once this is applied. This applies also for the PF_BRIDGE and fdb iproute2 patches. iproute2 patches are now available here: https://github.com/jpirko/iproute2-rocker For detailed description and version history, please see individual patches. In v4 I reordered the patches leaving rocker patches on the end of the patchset. In v5 I only fixed whitespace issues of patch #13 We have a TODO for related items we want to work on in near future: https://etherpad.wikimedia.org/p/netdev-swdev-todo Jiri Pirko (10): bridge: rename fdb_*_hw to fdb_*_hw_addr to avoid confusion neigh: sort Neighbor Cache Entry Flags bridge: convert flags in fbd entry into bitfields net: make vid as a parameter for ndo_fdb_add/ndo_fdb_del 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 rocker: introduce rocker switch driver rocker: implement ndo_fdb_dump Scott Feldman (9): bridge: call netdev_sw_port_stp_update when bridge port STP status changes bridge: add API to notify bridge driver of learned FBD on offloaded device bridge: move private brport flags to if_bridge.h so port drivers can use flags bridge: add new brport flag LEARNING_SYNC bridge: add new hwmode swdev bridge: add brport flags to dflt bridge_getlink rocker: implement rocker ofdpa flow table manipulation rocker: implement L2 bridge offloading rocker: add ndo_bridge_setlink/getlink support for learning policy Thomas Graf (2): rocker: Add proper validation of Netlink attributes rocker: Use logical operators on booleans Documentation/ABI/testing/sysfs-class-net | 8 + Documentation/networking/switchdev.txt | 59 + MAINTAINERS | 14 + drivers/net/ethernet/Kconfig | 1 + drivers/net/ethernet/Makefile | 1 + drivers/net/ethernet/broadcom/bnx2x/bnx2x_main.c | 2 +- drivers/net/ethernet/emulex/benet/be_main.c | 3 +- drivers/net/ethernet/intel/i40e/i40e_main.c | 4 +- drivers/net/ethernet/intel/ixgbe/ixgbe_main.c | 6 +- drivers/net/ethernet/mellanox/mlx4/en_netdev.c | 2 +- drivers/net/ethernet/qlogic/qlcnic/qlcnic_main.c | 11 +- drivers/net/ethernet/rocker/Kconfig | 27 + drivers/net/ethernet/rocker/Makefile | 5 + drivers/net/ethernet/rocker/rocker.c | 4374 ++++++++++++++++++++++ drivers/net/ethernet/rocker/rocker.h | 428 +++ drivers/net/macvlan.c | 4 +- drivers/net/vxlan.c | 4 +- include/linux/if_bridge.h | 31 + include/linux/netdevice.h | 39 +- include/linux/rtnetlink.h | 9 +- include/net/switchdev.h | 37 + include/uapi/linux/if_bridge.h | 1 + include/uapi/linux/if_link.h | 2 + include/uapi/linux/neighbour.h | 6 +- net/Kconfig | 1 + net/Makefile | 3 + net/bridge/br_fdb.c | 144 +- net/bridge/br_private.h | 21 +- net/bridge/br_stp.c | 7 + net/core/dev.c | 2 +- net/core/net-sysfs.c | 26 +- net/core/rtnetlink.c | 119 +- net/switchdev/Kconfig | 13 + net/switchdev/Makefile | 5 + net/switchdev/switchdev.c | 52 + 35 files changed, 5366 insertions(+), 105 deletions(-) create mode 100644 Documentation/networking/switchdev.txt 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 net/switchdev/Kconfig create mode 100644 net/switchdev/Makefile create mode 100644 net/switchdev/switchdev.c -- 1.9.3
