This is used for multiple purposes, depending on the scheduling element
created. There are a few helper struct defined a long time ago, but they
are not easy to find in the file and they are about to get new members.
This commit cleans up this area a bit by:
- moving the helper structs closer to where they are relevant.
- defining a helper union to include all of them to help
  discoverability.
- making use of it everywhere element_attributes is used.
- using a consistent 'attr' name.

The mlx5_fc_stats and mlx5_fc_pool structs are only used from
fs_counters.c. As such, make them private there.

mlx5_fc_pool is not used or referenced at all outside fs_counters.

mlx5_fc_stats is referenced from mlx5_core_dev, so instead of having it
as a direct member (which requires exporting it from fs_counters), store
a pointer to it, allocate it on init and clear it on destroy.
One caveat is that a simple container_of to get from a 'work' struct to
the outermost mlx5_core_dev struct directly no longer works, so an extra
pointer had to be added to mlx5_fc_stats back to the parent dev.

Fixing the wrong size of a field in hca_cap_2.
The bug was introduced by adding new fields for HWS
and not fixing the reserved field size.

Pull rdma updates from Jason Gunthorpe:
 "Usual collection of small improvements and fixes, nothing especially
  stands out to me here.

  The new multipath PCI feature is a sign of things to come, I think we
  will see more of this in the next 10 years. Broadcom and HNS continue
  to update their drivers for their new HW generations.

  Summary:

   - Bug fixes and minor improvments in cxgb4, siw, mlx5, rxe, efa, rts,
     hfi, erdma, hns, irdma

   - Code cleanups/typos/etc. Tidy alloc_ordered_workqueue() calls

   - Multipath PCI for mlx5

   - Variable size work queue, SRQ changes, and relaxed ordering for new
     bnxt HW

   - New ODP fault resolution FW protocol in mlx5

   - New 'rdma monitor' netlink mechanism"

The IB layer provides a common interface to store and get net
devices associated to an IB device port (ib_device_set_netdev()
and ib_device_get_netdev()).
Previously, mlx5_ib stored and managed the associated net devices
internally.

Replace internal net device management in mlx5_ib with
ib_device_set_netdev() when attaching/detaching  a net device and
ib_device_get_netdev() when retrieving the net device.

Export ib_device_get_netdev().

For mlx5 representors/PFs/VFs and lag creation we replace the netdev
assignments with the IB set/get netdev functions.

In active-backup mode lag the active slave net device is stored in the
lag itself. To assure the net device stored in a lag bond IB device is
the active slave we implement the following:
- mlx5_core: when modifying the slave of a bond we send the internal driver event
  MLX5_DRIVER_EVENT_ACTIVE_BACKUP_LAG_CHANGE_LOWERSTATE.
- mlx5_ib: when catching the event call ib_device_set_netdev()

This patch also ensures the correct IB events are sent in switchdev lag.

While at it, when in multiport eswitch mode, only a single IB device is
created for all ports. The said IB device will receive all netdev events
of its VFs once loaded, thus to avoid overwriting the mapping of PF IB
device to PF netdev, ignore NETDEV_REGISTER events if the ib device has
already been mapped to a netdev.

When running over new FW that supports the new memory scheme ODP, set
the cap in the FW to signal the FW we are working in the new scheme.

In the memory scheme ODP the per_transport_service capabilities are RO
for the driver so we skip their setting.
