2023-12-20net/mlx5e: Block TLS device offload on combined SD netdevTariq Toukan
1) Each TX TLS device offloaded context has its own TIS object. Extra work is needed to get it working in a SD environment, where a stream can move between different SQs (belonging to different mdevs). 2) Each RX TLS device offloaded context needs a DEK object from the DEK pool. Extra work is needed to get it working in a SD environment, as the DEK pool currently falsely depends on TX cap, and is on the primary device only. Disallow this combination for now.

2023-12-20net/mlx5e: Support per-mdev queue counterTariq Toukan
Each queue counter object counts some events (in hardware) for the RQs that are attached to it, like events of packet drops due to no receive WQE (rx_out_of_buffer). Each RQ can be attached to a queue counter only within the same vhca. To still cover all RQs with these counters, we create multiple instances, one per vhca. The result that's shown to the user is now the sum of all instances. Signed-off-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>

Implement driver support for the HW feature that allows RX steering of one device to target other device's RQs. In SD multi-mdev netdev mode, we set the secondaries into silent mode, disconnecting them from the network. This feature is then used to steer traffic from the primary to the secondaries.

2023-12-20net/mlx5e: Let channels be SD-awareTariq Toukan
Distribute the channels between the different SD-devices to acheive local numa node performance on multiple numas. Each channel works against one specific mdev, creating all datapath queues against it. We distribute channels to mdevs in a round-robin policy. Example for 2 mdevs and 6 channels: +-------+---------+ | ch ix | mdev ix | +-------+---------+ | 0 | 0 | | 1 | 1 | | 2 | 0 | | 3 | 1 | | 4 | 0 | | 5 | 1 | +-------+---------+ This round-robin distribution policy is preferred over another suggested intuitive distribution, in which we first distribute one half of the channels to mdev #0 and then the second half to mdev #1. We prefer round-robin for a reason: it is less influenced by changes in the number of channels. The mapping between channel index and mdev is fixed, no matter how many channels the user configures. As the channel stats are persistent to channels closure, changing the mapping every single time would turn the accumulative stats less representing of the channel's history. Per-channel objects should stop using the primary mdev (priv->mdev) directly, and instead move to using their own channel's mdev.

2023-12-20net/mlx5: SD, Implement steering for primary and secondariesTariq Toukan
Implement the needed SD steering adjustments for the primary and secondaries. While the SD multiple devices are used to avoid cross-numa memory, when it comes to chip level all traffic goes only through the primary device. The secondaries are forced to silent mode, to guarantee they are not involved in any unexpected ingress/egress traffic. In RX, secondary devices will not have steering objects. Traffic will be steered from the primary device to the RQs of a secondary device using advanced cross-vhca RX steering capabilities. In TX, the primary creates a new TX flow table, which is aliased by the secondaries. Signed-off-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
2023-12-20net/mlx5: SD, Implement devcom communication and primary electionTariq Toukan
Use devcom to communicate between the different devices. Add a new devcom component type for this. Each device registers itself to the devcom component <SD, group ID>. Once all devices of a component are registered, the component becomes ready, and a primary device is elected. In principle, any of the devices can act as a primary, they are all capable, and a random election would've worked. However, we aim to achieve predictability and consistency, hence each group always choses the same device, with the lowest PCI BUS number, as primary.
