The format of 802.1ad tag is the same as\n802.1q, except it uses the EtherType of 0x88a8, unlike 802.1q's 0x8100.\n\nCurrently, mlxsw supports bridging with VLAN-unaware (802.1d) bridges\nand with VLAN-aware bridges whose VLAN protocol is 802.1q. This set adds\nsupport for VLAN-aware bridges whose VLAN protocol is 802.1ad.\n\nFrom mlxsw perspective, 802.1ad support entails two main changes:\n\n1. Ports member in an 802.1ad bridge need to be configured to classify\n802.1ad packets as tagged and all other packets as untagged\n\n2. When pushing a VLAN at ingress (PVID), its EtherType needs to be\n0x88a8 instead of 802.1q's 0x8100\n\nThe rest stays the same as with 802.1q bridges.\n\nA follow-up patch set will add support for QinQ with VXLAN, also known\nas QinVNI. Currently, linking of a VXLAN netdev to an 802.1ad bridge is\nvetoed and an error is returned to user space.\n\nPatch set overview:\n\nPatches #1-#2 add the registers required to configure the two changes\ndescribed above.\n\nPatch #3 changes the device to only treat 802.1q packets as tagged by\ndefault, as opposed to both 802.1q and 802.1ad packets. This is more\ninline with the behavior supported by the driver.\n\nPatch #4 adds the ability to configure the EtherType when pushing a PVID\nat ingress.\n\nPatch #5 performs small refactoring to allow for code re-use in the next\npatch.\n\nPatch #6 adds support for 802.1ad bridging and allows mlxsw ports and\ntheir uppers to join such a bridge.\n\nPatch #7 changes the bridge driver to notify about changes to its VLAN\nprotocol, so that these could be vetoed by mlxsw in the next patch.\n\nPatches #8-#9 teach mlxsw to veto unsupported 802.1ad configurations and\nadd a corresponding selftest to make sure such configurations are indeed\nvetoed.\n\nAmit Cohen (6):\n mlxsw: reg: Add Switch Port VLAN Classification Register\n mlxsw: reg: Add et_vlan field to SPVID register\n mlxsw: spectrum: Only treat 802.1q packets as tagged packets\n mlxsw: Make EtherType configurable when pushing VLAN at ingress\n mlxsw: spectrum_switchdev: Create common functions for VLAN-aware\n bridge\n mlxsw: spectrum_switchdev: Add support of QinQ traffic\n\nDanielle Ratson (3):\n bridge: switchdev: Notify about VLAN protocol changes\n mlxsw: Add QinQ configuration vetoes\n selftests: forwarding: Add QinQ veto testing\n\n drivers/net/ethernet/mellanox/mlxsw/reg.h | 114 ++++++-\n .../net/ethernet/mellanox/mlxsw/spectrum.c | 111 ++++++-\n .../net/ethernet/mellanox/mlxsw/spectrum.h | 7 +-\n .../ethernet/mellanox/mlxsw/spectrum_router.c | 9 +\n .../mellanox/mlxsw/spectrum_switchdev.c | 123 +++++++-\n include/net/switchdev.h | 2 +\n net/bridge/br_vlan.c | 16 +-\n .../drivers/net/mlxsw/q_in_q_veto.sh | 296 ++++++++++++++++++\n 8 files changed, 657 insertions(+), 21 deletions(-)\n create mode 100755 tools/testing/selftests/drivers/net/mlxsw/q_in_q_veto.sh" }
