net/mlx5: Ethernet resource handling files This patch contains the resource handling files: - flow_table.c: This file contains the code to handle the low level API to configure hardware flow table. It is separated from the flow_table_en.c, because it will be used in the future by Raw Ethernet QP in mlx5_ib too. - en_flow_table.[ch]: Ethernet flow steering handling. The flow table object contain a mapping between flow specs and TIRs. This mechanism will be used also to configure e-switch in the future, when SR-IOV support will be added. - transobj.[ch] - Low level functions to create/modify/destroy the transport objects: RQ/SQ/TIR/TIS - vport.[ch] - Handle attributes of a virtual port (vPort) in the embedded switch. Currently this switch is a passthrough, until SR-IOV support will be added. Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

It is not "natural" to place it at index 0 since we want to put the representor for vport 0 at index 0 with the introduction of SmartNIC.

MLX5_VPORT_PF = 0x0,
net/mlx5: E-Switch, Split VF and special vports for offloads mode When driver is entering offloads mode, there are two major tasks to do: initialize flow steering and create representors. Flow steering should make sure enough flow table/group spaces are reserved for all reps. Representors will be created in a group, all or none. With the introduction of ECPF, flow steering should still reserve the same spaces. But, the representors are not always loaded/unloaded in a single piece. Once ECPF is in offloads mode, it will get the number of VF changing event from host PF. In such scenario, only the VF reps should be loaded/unloaded, not the reps for special vports (such as the uplink vport). Thus, when entering offloads mode, driver should specify the total number of reps, and the number of VF reps separately. When leaving offloads mode, the cleanup should use the information self-contained in eswitch such as number of VFs. This patch doesn't change any functionality.

net/mlx5: E-Switch, Properly refer to host PF vport as other vport Commands referring to vports use the following scheme: 1. When referring to my own vport, put 0 in vport and 0 in other_vport. 2. When referring to another vport, put the vport number of the referred vport and put 1 in other_vport. It was assumed that driver is accessing other vport when vport number is greater than 0. With the above scheme, the case that ECPF eswitch manager is trying to access host PF vport will fall over with scheme 1 as the vport number is 0. This is apparently wrong as driver is trying to refer other vport. As such usage can only happen in the eswitch context, change relevant functions to provide other vport input properly.

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