Add explicit HW defined error values. For simplicity, keep counters for all statuses starting from 0, although currently status=0 is not used. Additionally, when HW signals an unexpected cable status, it is reported now rather than ignored. And status counter is now updated on errors. Signed-off-by:

After the following flow counters API refactoring: ("net/mlx5: Use flow counter IDs and not the wrapping cache object") flow counters private data structures mlx5_fc_cache and mlx5_fc are redundantly exposed in fs_core.h, they have nothing to do with flow steering core and they are private to fs_counter.c, this patch moves them to where they belong and reduces their exposure in the driver.

Reuse existing infrastructure to initialize and release DEVX uid. The DevX interface is intended for user space access, so it is supposed to be initialized before ib_register_device(). Also it isn't supported in switchdev mode and don't need to initialize it in that mode. Fixes: 76dc5a84 ("IB/mlx5: Manage device uid for DEVX white list commands") Reviewed-by:

As a preparation to move SRQ functionality to RDMA, drop all references to mlx5_core logic and make SRQ be dependent on shared code only. Most of the time, we are interested to know if events are working/not working and it is possible with previous commit ("net/mlx5: Debug print for forwarded async events"). Reviewed-by:

Before the new mlx5 event notification infrastructure and API, mlx5_core used to process all events before forwarding them to mlx5 interfaces (mlx5e/mlx5_ib) and used to translate the event type enum to a software defined enum, this is not needed anymore since it is ok for mlx5e and mlx5_ib to receive FW events as is, at least the few ones mlx5 core allows. mlx5e and mlx5_ib already moved to use the new API and they only handle FW events types, it is now safe to remove all equivalent software defined events and the logic around them.

The mlx5_interface->event callback is not used by mlx5e/mlx5_ib anymore. We totally remove the delayed events logic work around, since with the dynamic notifier registration API it is not needed anymore, mlx5_ib can register its notifier and start receiving events exactly at the moment it is ready to handle them.

Remove the deprecated mlx5_interface->event mlx5_ib callback and use new mlx5 notifier API to subscribe for mlx5 events. For native mlx5_ib devices profiles pf_profile/nic_rep_profile register the notifier callback mlx5_ib_handle_event which treats the notifier context as mlx5_ib_dev. For vport repesentors, don't register any notifier, same as before, they didn't receive any mlx5 events. For slave port (mlx5_ib_multiport_info) register a different notifier callback mlx5_ib_event_slave_port, which knows that the event is coming for mlx5_ib_multiport_info and prepares the event job accordingly. Before this on the event handler work we had to ask mlx5_core if this is a slave port mlx5_core_is_mp_slave(work->dev), now it is not needed anymore. mlx5_ib_multiport_info notifier registration is done on mlx5_ib_bind_slave_port and de-registration is done on mlx5_ib_unbind_slave_port.

The idea is to allow mlx5 core interfaces (mlx5e/mlx5_ib) to be able to receive some allowed FW events as is via the new notifier API. In this patch we allow forwarding port change event to mlx5 core interfaces (mlx5e/mlx5_ib) as it was received from FW. Once mlx5e and mlx5_ib start using this event we can safely remove the redundant software version of it and its translation logic. Signed-off-by:

Use atomic notifier chain to fire events to mlx5 core driver consumers (mlx5e/mlx5_ib) and provide mlx5 register/unregister notifier API. This API will replace the current mlx5_interface->event callback and all the logic around it, especially the delayed events logic introduced by commit 97834eba ("net/mlx5: Delay events till ib registration ends") Which is not needed anymore with this new API where the mlx5 interface can dynamically register/unregister its notifier.
