Change that back to mlx5e_get_num_lag_ports(mdev). Also IPoIB interfaces create there own TISes, they don't use the eth TISes, pass a flag to indicate that.

Add a new devcom component type for this. Each device registers itself to the devcom component . 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.

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.

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.

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.

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.
