[ewg] [PATCHv8 0/11] IBoE support to Infiniband

IBoE allows running the IB transport protocol using Ethernet frames, enabling the deployment of IB semantics on lossless Ethernet fabrics. IBoE packets are standard Ethernet frames with an IEEE assigned Ethertype, a GRH, unmodified IB transport headers and payload. IB subnet management and SA

[ewg] [PATCHv8 01/11] ib core: Add link layer property to ports

This patch adds the infrastructure for querying the link layer of a port, which can be either IB_LINK_LAYER_INFINIBAND or IB_LINK_LAYER_ETHERNET. This is required for adding IBoE support to Infiniband drivers so that branching decisions can be made according to the value of this property. For

[ewg] [PATCHv8 02/11] ib_core: IBoE support only QP1

Since IBoE is using Ethernet as its link layer, there is no central management entity so there is need for QP0. QP1 is still needed since it handles communications between CM agents. This patch will create only QP1 for IBoE ports. Signed-off-by: Eli Cohen e...@mellanox.co.il --- Changes from v7:

[ewg] [PATCHv8 04/11] ib_core: IBoE CMA device binding

Add support for IBoE device binding and IP -- GID resolution. Path resolving and multicast joining are implemented within cma.c by filling the responses and pushing the callbacks to the cma work queue. IP-GID resolution always yields IPv6 link local addresses - remote GIDs are derived from the

[ewg] [PATCHv8 05/11] ib_core: IBoE UD packet packing support

Add support functions to aid in packing IBoE packets. Signed-off-by: Eli Cohen e...@mellanox.co.il --- drivers/infiniband/core/ud_header.c | 100 ++ include/rdma/ib_pack.h | 29 +- 2 files changed, 92 insertions(+), 37 deletions(-) Changes

[ewg] [PATCHv8 06/11] ipoib: avoid ipoib over IBoE

IPoIB is an implementation of IP over Infiniband transport. In the case of IBoE, the link layer is Ethernet so IP can work directly over Ethernet, so disable IPoIB for none IB_LINK_LAYER_INFINIBAND ports. Signed-off-by: Eli Cohen e...@mellanox.co.il --- drivers/infiniband/ulp/ipoib/ipoib_main.c

[ewg] [PATCHv8 07/11] ib_core: Add API to support IBoE from userspace

Add ib_uverbs_get_eth_l2_addr() to allow ibv_create_ah() to resolve sgid, dgid to vlan, dmac for any gid type. Although user-space might bypass this call for link-local gids, it is better not to replicate the kernel resolution policy. Port link layer is also returned by ibv_query_port().

[ewg] [PATCHv8 09/11] mlx4: Add support for IBoE - address resolution

The following patch handles address vectors creation for IBoE ports. mlx4 needs the MAC address of the remote node to include it in the WQE of a UD QP or in the QP context of connected QPs. Address resolution is done atomically in the case of a link local address or a multicast GID and otherwise

[ewg] [PATCHv8 10/11] ib_core: Add VLAN support to IBoE

Add 802.1q vlan support to IBoE. The vlan tag is encoded within the GID derived from a link local address in the following way: GID[11] GID[12] contain the vlan ID. The 3 bit user priority field is identical to the 3 bits of the SL. In case rdma_cm apps, the TOS field is used to generate the SL

[ewg] [PATCHv8 11/11] mlx4: Add vlan support to IBoE

This patch allows IBoE traffic to be encapsulated in 802.1q tagged VLAN frames. The VLAN tag is encoded in the GID and derived from it by a simple computation. The netdev notifier callback is modified to catch new VLAN devices addition/removal and the port's GID table is updated to reflect the

[ewg] [PATCHv8 1/4] libibverbs: Add link layer field to ibv_port_attr

This field can have one of the values - IBV_LINK_LAYER_UNSPECIFIED, IBV_LINK_LAYER_INFINIBAND, IBV_LINK_LAYER_ETHERNET. It can be used by applications to know the link layer used by the port, which can be either Infiniband or Ethernet. The addition of the new field does not change the size of

[ewg] [PATCHv8 2/4] libibverbs: change kernel API to accept link layer

Modify the code to allow passing the link layer of a port from kernel to user. Update ibv_query_port.3 man page with the change. Signed-off-by: Eli Cohen e...@mellanox.co.il --- include/infiniband/kern-abi.h |3 ++- man/ibv_query_port.3 |1 + src/cmd.c |1

[ewg] [PATCHv8 3/4] libibverbs: Add API to retrieve eth link layer address

Add a command to retrieve the layer 2 address of an ethernet port. The layer 2 address is comprised of the port's MAC address and the VLAN ID.This is required by libraries to build work requests when the port's link layer is Ethernet. Signed-off-by: Eli Cohen e...@mellanox.co.il ---

[ewg] [PATCHv8 4/4] libibverbs: Update examples for IBoE

Since IBoE requires usage of GRH, update ibv_*_pinpong examples to accept GIDs. GIDs are given as an index to the local port's table and are exchanged between the client and the server through the socket connection. The examples are also modified to pass the gid index to the code that creates the

[ewg] [PATCHv8 1/2] libmlx4: Add IBoE support

Modify libmlx4 to support IBoE. The change involves retrieving the ethernet layer 2 address of a port based on its GID and source index through a new system call, ibv_cmd_eth_l2_addr(), and embedding the layer 2 information in the address vector representation of mlx4. Signed-off-by: Eli Cohen
