    "content": "Hi Dave\n\nThis series provides two security SRIOV related features (VGT+ and VF violation counters).\n\nVGT+ is a security feature that gives the administrator the ability of controlling\nthe allowed VGT vlan IDs list that can be transmitted/received from/to the VF.\nThe allowed VGT vlan IDs list is called \"trunk\".\n\nAdmin can add/remove a range of allowed vlan-ids via iptool:\nip link set { DEVICE } [ vf NUM [ trunk { add | rem } START-VLAN-ID [ END-VLAN-ID ] [ proto VLAN-PROTO ] ] ]\n\nExample:\nAfter this series of configuration :\n1) ip link set eth3 vf 0 trunk add 10 100 (allow vlan-id 10-100, default tpid 0x8100)\n2) ip link set eth3 vf 0 trunk add 105 proto 802.1q (allow vlan-id 105 tpid 0x8100)\n3) ip link set eth3 vf 0 trunk add 105 proto 802.1ad (allow vlan-id 105 tpid 0x88a8)\n4) ip link set eth3 vf 0 trunk rem 90 (block vlan-id 90)\n5) ip link set eth3 vf 0 trunk rem 50 60 (block vlan-ids 50-60)\n\nVF 0 can only communicate on vlan-ids: 10-49,61-89,91-100,105 with tpid 0x8100 and vlan-id 105 with tpid 0x88a8.\n\nFor this purpose following net_device callbacks were added:\nint (*ndo_add_vf_vlan_trunk_range)(struct net_device *dev, int vf, u16 start_vid, u16 end_vid, __be16 proto);\nint (*ndo_del_vf_vlan_trunk_range)(struct net_device *dev, int vf, u16 start_vid, u16 end_vid, __be16 proto);\n\nThis feature is implemented and demonstrated in mlx5 via ACL steering tables and vlan rules attached to the VF's\ncorresponding E-Switch vport.\n\nI addition to VGT+ we introduce new set of counter to VF statistics, to collect counters for traffic violating\nVF ACL rules (such as VGT+ violation), for that we extend the current ifla_vf_stats to include rx_dropped/tx_dropped\nto be reported per VF.\n\nExample:\n> ip link set eth3 vf 0 trunk add 10 100\nVF 0 transmits 2412 packets on a vlan id not in [10,100] range will be dropped and reported in hypervisor\nvia:\n> ip -s link show dev enp5s0f0\"\n      6: enp5s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000\n        [...]\n\tvf 0 MAC 00:00:ca:fe:ca:fe, vlan 5, spoof checking off, link-state auto, trust off, query_rss off\n        RX: bytes  packets  mcast   bcast   dropped\n        1666       29       14         32      0\n        TX: bytes  packets   dropped\n        2880       44       2412\n\nThanks,\nSaeed.\n\nEugenia Emantayev (2):\n  net/core: Add violation counters to VF statisctics\n  net/mlx5e: E-switch, Add steering drop counters\n\nMohamad Haj Yahia (2):\n  net: Add SRIOV VGT+ support\n  net/mlx5: Add SRIOV VGT+ support\n\n drivers/net/ethernet/mellanox/mlx5/core/en_main.c  |  28 +\n drivers/net/ethernet/mellanox/mlx5/core/eswitch.c  | 589 +++++++++++++++++----\n drivers/net/ethernet/mellanox/mlx5/core/eswitch.h  |  31 +-\n drivers/net/ethernet/mellanox/mlx5/core/fs_core.h  |   2 +\n .../net/ethernet/mellanox/mlx5/core/fs_counters.c  |   6 +\n drivers/net/ethernet/mellanox/mlx5/core/vport.c    |  19 +-\n include/linux/if_link.h                            |   4 +\n include/linux/mlx5/vport.h                         |   6 +-\n include/linux/netdevice.h                          |  12 +\n include/uapi/linux/if_link.h                       |  22 +\n net/core/rtnetlink.c                               | 119 +++--\n 11 files changed, 681 insertions(+), 157 deletions(-)"
