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.

This patch offloads port mirroring directives to hw using the matchall TC with action mirror. It includes both the implementation of the ndo_setup_tc function for the spectrum driver and the spectrum hardware offload configuration code. The hardware offload code is basically two new functions which are capable of adding and removing a new mirror ports pair. It is done using the MPAT, MPAR and SBIB registers: - A new Switch-Port Analyzer (SPAN) entry is added using MPAT to the 'to' port. - The 'to' port is bound to the SPAN entry using MPAR register. - In case of egress SPAN, the 'to' port gets a new internal shared buffer using SBIB register. In addition, a new database was added to the mlxsw_sp struct to store all the SPAN entries and their bound ports list. The number of supported SPAN entries is determined by resource query.

A user will now be able to loop packets back out of the same port using a bpf program attached to xdp hook. Updates to the packet contents from the bpf program is also supported. For the packet write feature to work, the rx buffers are now mapped as bidirectional when the page is allocated. This occurs only when the xdp hook is active. When the program returns a TX action, enqueue the packet directly to a dedicated tx ring, so as to avoid completely any locking. This requires the tx ring to be allocated 1:1 for each rx ring, as well as the tx completion running in the same softirq. Upon tx completion, this dedicated tx ring recycles pages without unmapping directly back to the original rx ring. In steady state tx/drop workload, effectively 0 page allocs/frees will occur. In order to separate out the paths between free and recycle, a free_tx_desc func pointer is introduced that is optionally updated whenever recycle_ring is activated. By default the original free function is always initialized. Signed-off-by: NBrenden Blanco <bblanco@plumgrid.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
