    "content": "This patch series is meant to allow support for the L2 forward offload, aka\nMACVLAN offload without the need for using ndo_select_queue.\n\nThe existing solution currently requires that we use ndo_select_queue in\nthe transmit path if we want to associate specific Tx queues with a given\nMACVLAN interface. In order to get away from this we need to repurpose the\ntc_to_txq array and XPS pointer for the MACVLAN interface and use those as\na means of accessing the queues on the lower device. As a result we cannot\noffload a device that is configured as multiqueue, however it doesn't\nreally make sense to configure a macvlan interfaced as being multiqueue\nanyway since it doesn't really have a qdisc of its own in the first place.\n\nI am submitting this as an RFC for the netdev mailing list, and officially\nsubmitting it for testing to Jeff Kirsher's next-queue in order to validate\nthe ixgbe specific bits.\n\nThe big changes in this set are:\n  Allow lower device to update tc_to_txq and XPS map of offloaded MACVLAN\n  Disable XPS for single queue devices\n  Replace accel_priv with sb_dev in ndo_select_queue\n  Add sb_dev parameter to fallback function for ndo_select_queue\n  Consolidated ndo_select_queue functions that appeared to be duplicates\n\nv2:\nUpdated patch set to rebase the netdev_pick_tx logic off of recent Rx\nsymmetric queue changes.\n\n---\n\nAlexander Duyck (7):\n      net-sysfs: Drop support for XPS and traffic_class on single queue device\n      net: Add support for subordinate device traffic classes\n      ixgbe: Add code to populate and use macvlan tc to Tx queue map\n      net: Add support for subordinate traffic classes to netdev_pick_tx\n      net: Add generic ndo_select_queue functions\n      net: allow ndo_select_queue to pass netdev\n      net: allow fallback function to pass netdev\n\n\n drivers/infiniband/hw/hfi1/vnic_main.c            |    2 \n drivers/infiniband/ulp/opa_vnic/opa_vnic_netdev.c |    4 -\n drivers/net/bonding/bond_main.c                   |    3 \n drivers/net/ethernet/amazon/ena/ena_netdev.c      |    5 -\n drivers/net/ethernet/broadcom/bcmsysport.c        |    6 -\n drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c   |    6 +\n drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.h   |    3 \n drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c   |    5 -\n drivers/net/ethernet/hisilicon/hns/hns_enet.c     |    5 -\n drivers/net/ethernet/intel/ixgbe/ixgbe_main.c     |   62 ++++++--\n drivers/net/ethernet/lantiq_etop.c                |   10 -\n drivers/net/ethernet/mellanox/mlx4/en_tx.c        |    7 +\n drivers/net/ethernet/mellanox/mlx4/mlx4_en.h      |    3 \n drivers/net/ethernet/mellanox/mlx5/core/en.h      |    3 \n drivers/net/ethernet/mellanox/mlx5/core/en_tx.c   |    5 -\n drivers/net/ethernet/renesas/ravb_main.c          |    3 \n drivers/net/ethernet/sun/ldmvsw.c                 |    3 \n drivers/net/ethernet/sun/sunvnet.c                |    3 \n drivers/net/ethernet/ti/netcp_core.c              |    9 -\n drivers/net/hyperv/netvsc_drv.c                   |    6 -\n drivers/net/macvlan.c                             |   10 -\n drivers/net/net_failover.c                        |    7 +\n drivers/net/team/team.c                           |    3 \n drivers/net/tun.c                                 |    3 \n drivers/net/wireless/marvell/mwifiex/main.c       |    3 \n drivers/net/xen-netback/interface.c               |    4 -\n drivers/net/xen-netfront.c                        |    3 \n drivers/staging/netlogic/xlr_net.c                |    9 -\n drivers/staging/rtl8188eu/os_dep/os_intfs.c       |    3 \n drivers/staging/rtl8723bs/os_dep/os_intfs.c       |    7 -\n include/linux/netdevice.h                         |   34 ++++-\n net/core/dev.c                                    |  157 ++++++++++++++++++---\n net/core/net-sysfs.c                              |   36 ++++-\n net/mac80211/iface.c                              |    4 -\n net/packet/af_packet.c                            |    7 +\n 35 files changed, 312 insertions(+), 131 deletions(-)\n\n--"
