Used by IB driver for determining the IB bond device's netdev, when LAG is active. Returns PF0's netdev if mode is not active-backup, or the PF netdev of the active slave when mode is active-backup.

Available on dual port cards only, this feature keeps track, using netdev LAG events, of the bonding and link status of each port's PF netdev. When both of the card's PF netdevs are enslaved to the same bond/team master, and only them, LAG state is active. During LAG, only one IB device is present for both ports. In addition to the above, this commit includes FW commands used for managing the LAG, new facilities for adding and removing a single device by interface, and port remap functionality according to bond events. Please note that this feature is currently used only for mimicking Ethernet bonding for RoCE - netdevs functionality is not altered, and their bonding continues to be managed solely by bond/team driver.

Exposed LAG commands enum and layouts: - CREATE_LAG HW enters LAG mode: RoCE traffic from port two is received on PF0 core dev. Allows to set tx_affinity (tx port) for QPs and TISes. Allows to port remap QPs and TISes, overriding their tx_affinity behavior. - MODIFY_LAG Remap QPs and TISes to another port. - QUERY_LAG Query whether LAG mode is active. - DESTROY_LAG HW exits LAG mode, returning to non-LAG behavior. - CREATE_VPORT_LAG Merge Ethernet flow steering, such that traffic received on port two jumps to PF0 root flow table. Available only in LAG mode. - DESTROY_VPORT_LAG Ethernet flow steering returns to non-LAG behavior. Caps added: - lag_master Driver is in charge of managing the LAG. This is currently the only option. - num_lag_ports LAG is supported only if this field's value is 2. Other fields: - QP/TIS tx port affinity During LAG, this field controls on which port a QP or TIS resides. - TIS strict tx affinity When this field is set, the TIS will not be subject to port remap by CREATE_LAG/MODIFY_LAG. - LAG demux flow table Flow table used for redirecting non user-space traffic back to PF1 root flow table, if the packet was received on port two.

Prior to this patch we assumed that modify QP commands have the same layout. In ConnectX-4 for each QP transition there is a specific command and their layout can vary. e.g: 2err/2rst commands don't have QP context in their layout and before this patch we posted the QP context in those commands. Fortunately the FW only checks the suffix of the commands and executes them, while ignoring all invalid data sent after the valid command layout. This patch removes mlx5_modify_qp_mbox_in and changes mlx5_core_qp_modify to receive the required transition and QP context with opt_param_mask if needed. This way the caller is not required to provide the command inbox layout and it will be generated automatically. mlx5_core_qp_modify will generate the command inbox/outbox layouts according to the requested transition and will fill the requested parameters.

The workqueue health->wq was used as per device private health thread. This was done to perform delayed work. The workqueue has a single workitem(&health->work) and hence doesn't require ordering. It is involved in handling the health of the device and is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. Work item has been flushed in mlx5_health_cleanup() to ensure that there are no pending tasks while disconnecting the driver.

Add support for query the minimum inline mode from the Firmware. It is required for correct TX steering according to L3/L4 packet headers. Each send queue (SQ) has inline mode that defines the minimal required headers that needs to be copied into the SQ WQE. The driver asks the Firmware for the wqe_inline_mode device capability value. In case the device capability defined as "vport context" the driver must check the reported min inline mode from the vport context before creating its SQs.

In the offloads mode, some slow path rules are added by the driver (e.g send-to-vport), while offloaded rules are to be added from upper layers. The slow path rules have lower priority and we don't want matching on offloaded rules to suffer from extra steering hops related to the slow path rules. We use two priorities, one for offloaded rules (fast path), and one for the control rules (slow path). To allow for that, we enable two priorities for the FDB namespace in the FS core code.

This commit utilize the ability of ConnectX-4 to bulk read flow counters. Few bulk counter queries could be done instead of issuing thousands of firmware commands per second to get statistics of all flows set to HW, such as those programmed when we offload tc filters. Counters are stored sorted by hardware id, and queried in blocks (id + number of counters). Due to hardware requirement, start of block and number of counters in a block must be four aligned.

Start all tx queues (including inactive ones) when opening the netdev. Stop all tx queues (including inactive ones) when closing the netdev. This is a workaround for the tx timeout watchdog false alarm issue in which the netdev watchdog is polling all the tx queues which may include inactive queues and thus once lowering the real tx queues number (ethtool -L) it will generate tx timeout watchdog false alarms.
