net/mlx5: Add timeout handle to commands with callback

2016-07-01T10:12:03+00:00

The current implementation does not handle timeout in case of command with callback request, and this can lead to deadlock if the command doesn't get fw response. Add delayed callback timeout work before posting the command to fw. In case of real fw command completion we will cancel the delayed work. In case of fw command timeout the callback timeout handler will be called and it will simulate fw completion with timeout error.

IB/mlx5: Fix post send fence logic

2016-06-23T14:03:57+00:00

If the caller specified IB_SEND_FENCE in the send flags of the work request and no previous work request stated that the successive one should be fenced, the work request would be executed without a fence. This could result in RDMA read or atomic operations failure due to a MR being invalidated. Fix this by adding the mlx5 enumeration for fencing RDMA/atomic operations and fix the logic to apply this.

net/mlx5: E-Switch, Modify node guid on vf set MAC

2016-06-10T05:06:26+00:00

In RoCE, the RDMA-CM needs the node guid to establish connection between nodes. Today, the node guid exposed to mlx5 Ethernet VFs is zero, therefore RDMA-CM on the VF is broken. Whenever the administrator sets a MAC for a VF, derive the node guid from it and set it as well in the following way: MAC: e4:1d:2d:b3:f4:01 -> node_guid: e4:1d:2d:ff:fe:b3:f4:01 Fixes: 77256579c6b43 ('net/mlx5: E-Switch, Introduce Vport...')

net/mlx5: Fix flow steering NIC capabilities check

2016-06-10T05:06:25+00:00

Flow steering infrastructure is currently used only on link layer ethernet, therefore the driver should initialize the flow steering when the device link layer is ethernet. In addition, add missing capability check before initializing the namespace of NIC RX flow tables.

net/mlx5: Fix MLX5_CMD_OP_MAX to be defined correctly

2016-06-10T05:06:25+00:00

Having MLX5_CMD_OP_MAX on another file causes us to repeatedly miss accounting new commands added to the driver and hence there're no entries for them in debugfs. To solve that, we integrate it into the commands enum as the last entry.

IB/mlx5: Fix pkey_index length in the QP path record

2016-06-07T14:03:50+00:00

Pkey index fields in the QP context path record are extended to 16 bits, as required by IB spec (version 1.3). This change affects all QP commands which include path records. To enable this change, moved the free adaptive routing flag bit (free_ar) to the most significant byte of the QP path record. Fixes: e126ba97dba9e ('mlx5: Add driver for Mellanox Connect-IB ...')
