| * {net,ib}/mlx5: Don't disable local loopback multicast traffic when neededEran Ben Elisha2018-01-121-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A DC Target (DCT) QP is represented in the hardware as a unique object. This object is created by CREATE_DCT command and destroyed by DESTROY_DCT command. However, in the driver we describe it as a QP. The hardware command that creates a DCT needs parameters that the verb create_qp() does not provide. Those remaining parameters are provided with the call to the verb modify_qp(). Therefore we delay the actual creation of a DCT in the hardware until the stage of modify_qp() to RTR. A support for query_qp() was added as well. It uses QUERY_DCT command to retrieve the applicable fields.

Currently upon alloc context there is some fix size of UARs that are allocated (named 'static allocation') and there is no option to user application to ask for more or control which UAR will be used by which QP. In this patch the driver prepares its data structures to manage both the static and the dynamic allocations and let the user driver knows about the max value of dynamic blue-flame registers that are allowed.

* IB/mlx5: fix debugfs cleanupSudip Mukherjee2017-09-221-3/+3
| | | | | | | | | | | | | | If delay_drop_debugfs_init() fails in any of the operations to create debugfs, it is calling delay_drop_debugfs_cleanup() as part of its cleanup. But delay_drop_debugfs_cleanup() checks for 'dbg' and since we have not yet pointed 'dbg' to the debugfs we need to cleanup, the cleanup fails and we are left with stray debugfs elements and also a memory leak.

* IB/mlx5: Add support for multi underlay QPYishai Hadas2017-08-241-7/+42
| | | | | | | | | | | | | | | | | | | | Set underlay QPN as part of flow rule when it's applicable. There is one root flow table in the NIC RX namespace and all the underlay QPs steer the traffic to this flow table. In order to prevent QP to get traffic which is not target to its underlay QP, we need to set the underlay QP number as part of the steering matching. Note: When multicast traffic is sent the QPN filtering is done by the firmware as some early step. Adding the QPN match on the flow table entry is wrong as by that time the target QPN holds the multicast address (e.g. FF(s)) and it won't match.

* IB/mlx5: Expose software parsing for Raw Ethernet QPNoa Osherovich2017-08-241-0/+21
| | | | | | | | | | | | | | | | | | Software parsing (SWP) is a feature that can be used to instruct the device to stop using its internal parser and to parse packets on the transmit path according to offsets set for each packets. Through this feature, the device allows the handling of checksum and LSO by the hardware according to the location of IP and TCP/UDP headers. Enable SW parsing on Raw Ethernet send queue by default if firmware supports it and report these capabilities to user space.
