net/mlx5: Enable setting hairpin queue size

2018-01-19T20:41:32Z

Allow to specify the size of the hairpin queues along with the packet buffer data size from the core setup code. If the driver doesn't provide this, the FW applies proper value that matches the provided data size and a FW chosen RQ stride size. Signed-off-by: Or Gerlitz Signed-off-by: Saeed Mahameed

net/mlx5: Fix build break

2018-01-17T16:24:28Z

The latest merge between net and net-next introduced a complier assert in mlx5 driver. In hca_cap_bits older fields are kept along with newer fields that should have replaced them.

{net,ib}/mlx5: Don't disable local loopback multicast traffic when needed

2018-01-11T22:52:42Z

There are systems platform information management interfaces (such as HOST2BMC) for which we cannot disable local loopback multicast traffic. Separate disable_local_lb_mc and disable_local_lb_uc capability bits so driver will not disable multicast loopback traffic if not supported. (It is expected that Firmware will not set disable_local_lb_mc if HOST2BMC is running for example.) Function mlx5_nic_vport_update_local_lb will do best effort to disable/enable UC/MC loopback traffic and return success only in case it succeeded to changed all allowed by Firmware. Adapt mlx5_ib and mlx5e to support the new cap bits.

net/mlx5: Add hairpin definitions to the FW API

{net, IB}/mlx5: Manage port association for multiport RoCE

2018-01-08T18:42:22Z

When mlx5_ib_add is called determine if the mlx5 core device being added is capable of dual port RoCE operation. If it is, determine whether it is a master device or a slave device using the num_vhca_ports and affiliate_nic_vport_criteria capabilities. If the device is a slave, attempt to find a master device to affiliate it with. Devices that can be affiliated will share a system image guid. If none are found place it on a list of unaffiliated ports. If a master is found bind the port to it by configuring the port affiliation in the NIC vport context. Similarly when mlx5_ib_remove is called determine the port type. If it's a slave port, unaffiliate it from the master device, otherwise just remove it from the unaffiliated port list. The IB device is registered as a multiport device, even if a 2nd port is not available for affiliation. When the 2nd port is affiliated later the GID cache must be refreshed in order to get the default GIDs for the 2nd port in the cache. Export roce_rescan_device to provide a mechanism to refresh the cache after a new port is bound. In a multiport configuration all IB object (QP, MR, PD, etc) related commands should flow through the master mlx5_core_dev, other commands must be sent to the slave port mlx5_core_mdev, an interface is provide to get the correct mdev for non IB object commands.

net/mlx5: Set software owner ID during init HCA

2018-01-08T18:42:20Z

Generate a unique 128bit identifier for each host and pass that value to firmware in the INIT_HCA command if it reports the sw_owner_id capability. Each device bound to the mlx5_core driver will have the same software owner ID. In subsequent patches mlx5_core devices will be bound via a new VPort command so that they can operate together under a single InfiniBand device. Only devices that have the same software owner ID can be bound, to prevent traffic intended for one host arriving at another. The INIT_HCA command length was expanded by 128 bits. The command length is provided as an input FW commands. Older FW does not have a problem receiving this command in the new longer form.

net/mlx5: Fix rate limit packet pacing naming and struct

2017-12-19T21:23:58Z

In mlx5_ifc, struct size was not complete, and thus driver was sending garbage after the last defined field. Fixed it by adding reserved field to complete the struct size. In addition, rename all set_rate_limit to set_pp_rate_limit to be compliant with the Firmware <-> Driver definition.
