Hi Dave, This series is built upon the code added in commit ce388ff "Merge branch 'mlx4-next'" which added HA and LAG support to mlx4 RoCE and SRIOV services.
We add HA and Link Aggregation support to single ported mlx4 Ethernet VFs. In this case, the PF Ethernet interfaces are bonded, the VFs see single port HW devices (already supported) -- however, now this port is highly available. This means that all VF HW QPs (both VF Ethernet driver and VF RoCE / RAW QPs) are subject to the V2P (Virtual-To-Physical) mapping which is managed by the PF driver, and hence resilient across link failures and such events. When bonding operates in Dynamic link aggregation (802.3ad) mode, traffic from each VF will go over the VF "base port" (the port this VF is assigned to by the admin) as long as this port is up. When the port fails, traffic from all VFs that are defined on this port will move to the other port, and be back to their base-port when it recovers. Moni and Or. Moni Shoua (4): net/mlx4_core: Use both physical ports to dispatch link state events to VF net/mlx4_core: Support mirroring VF DMFS rules on both ports net/mlx4_core: Keep VLAN/MAC tables mirrored in multifunc HA mode net/mlx4_core: Support the HA mode for SRIOV VFs too Or Gerlitz (2): net/mlx4_core: Use both physical ports to set the VF link state IB/mlx4: Use the VF base-port when demuxing mad from wire drivers/infiniband/hw/mlx4/mad.c | 17 +- drivers/net/ethernet/mellanox/mlx4/eq.c | 24 +- drivers/net/ethernet/mellanox/mlx4/fw.c | 12 +- drivers/net/ethernet/mellanox/mlx4/fw.h | 1 + drivers/net/ethernet/mellanox/mlx4/main.c | 107 +++- drivers/net/ethernet/mellanox/mlx4/mlx4.h | 8 + drivers/net/ethernet/mellanox/mlx4/port.c | 598 ++++++++++++++++++++- .../net/ethernet/mellanox/mlx4/resource_tracker.c | 193 ++++++- include/linux/mlx4/driver.h | 5 + 9 files changed, 915 insertions(+), 50 deletions(-) -- 2.3.7 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
