A new device capability bit, IB_DEVICE_RDMA_NETDEV_OPA, triggers ipoib to create a datagram QP using the IB_QP_CREATE_NETDEV_USE. The highlights include: - Sharing send and receive resources with VNIC - Allows for switching between connected mode and datagram mode - Increases the maximum datagram MTU for opa devices to 10k The same spreading capability exploited by VNIC is used here to vary the receive context that receives the packet. The patches are fully bisectable and stepwise implement the capability. --- Gary Leshner (6): IB/hfi1: Add functions to transmit datagram ipoib packets IB/hfi1: Add the transmit side of a datagram ipoib RDMA netdev IB/hfi1: Remove module parameter for KDETH qpns IB/{rdmavt,hfi1}: Implement creation of accelerated UD QPs IB/{hfi1,ipoib,rdma}: Broadcast ping sent packets which exceeded mtu size IB/ipoib: Add capability to switch between datagram and connected mode Grzegorz Andrejczuk (7): IB/hfi1: RSM rules for AIP IB/hfi1: Rename num_vnic_contexts as num_netdev_contexts IB/hfi1: Add functions to receive accelerated ipoib packets IB/hfi1: Add interrupt handler functions for accelerated ipoib IB/hfi1: Add rx functions for dummy netdev IB/hfi1: Activate the dummy netdev IB/hfi1: Add packet histogram trace event Kaike Wan (1): IB/hfi1: Add accelerated IP capability bit Piotr Stankiewicz (1): IB/hfi1: Enable the transmit side of the datagram ipoib netdev Sadanand Warrier (1): IB/ipoib: Increase ipoib Datagram mode MTU's upper limit drivers/infiniband/hw/hfi1/Makefile | 4 drivers/infiniband/hw/hfi1/affinity.c | 12 drivers/infiniband/hw/hfi1/affinity.h | 3 drivers/infiniband/hw/hfi1/chip.c | 303 ++++++--- drivers/infiniband/hw/hfi1/chip.h | 5 drivers/infiniband/hw/hfi1/common.h | 13 drivers/infiniband/hw/hfi1/driver.c | 231 ++++++- drivers/infiniband/hw/hfi1/file_ops.c | 4 drivers/infiniband/hw/hfi1/hfi.h | 38 - drivers/infiniband/hw/hfi1/init.c | 14 drivers/infiniband/hw/hfi1/ipoib.h | 171 +++++ drivers/infiniband/hw/hfi1/ipoib_main.c | 309 +++++++++ drivers/infiniband/hw/hfi1/ipoib_rx.c | 95 +++ drivers/infiniband/hw/hfi1/ipoib_tx.c | 828 ++++++++++++++++++++++++ drivers/infiniband/hw/hfi1/msix.c | 36 + drivers/infiniband/hw/hfi1/msix.h | 7 drivers/infiniband/hw/hfi1/netdev.h | 118 +++ drivers/infiniband/hw/hfi1/netdev_rx.c | 481 ++++++++++++++ drivers/infiniband/hw/hfi1/qp.c | 18 - drivers/infiniband/hw/hfi1/tid_rdma.c | 4 drivers/infiniband/hw/hfi1/trace.c | 42 + drivers/infiniband/hw/hfi1/trace_ctxts.h | 11 drivers/infiniband/hw/hfi1/verbs.c | 13 drivers/infiniband/hw/hfi1/vnic.h | 5 drivers/infiniband/hw/hfi1/vnic_main.c | 318 ++------- drivers/infiniband/sw/rdmavt/qp.c | 24 + drivers/infiniband/ulp/ipoib/ipoib_main.c | 25 - drivers/infiniband/ulp/ipoib/ipoib_multicast.c | 12 drivers/infiniband/ulp/ipoib/ipoib_verbs.c | 3 drivers/infiniband/ulp/ipoib/ipoib_vlan.c | 3 include/rdma/ib_verbs.h | 65 ++ include/rdma/opa_port_info.h | 10 include/rdma/opa_vnic.h | 4 include/rdma/rdmavt_qp.h | 29 + include/uapi/rdma/hfi/hfi1_user.h | 3 35 files changed, 2768 insertions(+), 493 deletions(-) create mode 100644 drivers/infiniband/hw/hfi1/ipoib.h create mode 100644 drivers/infiniband/hw/hfi1/ipoib_main.c create mode 100644 drivers/infiniband/hw/hfi1/ipoib_rx.c create mode 100644 drivers/infiniband/hw/hfi1/ipoib_tx.c create mode 100644 drivers/infiniband/hw/hfi1/netdev.h create mode 100644 drivers/infiniband/hw/hfi1/netdev_rx.c -- -Denny
