====================
ice: one by one port representors creation

Michal Swiatkowski says:

Currently ice supports creating port representors only for VFs. For that
use case they can be created and removed in one step.

This patchset is refactoring current flow to support port representor
creation also for subfunctions and SIOV. In this case port representors
need to be created and removed one by one. Also, they can be added and
removed while other port representors are running.

To achieve that we need to change the switchdev configuration flow.
Three first patches are only cosmetic (renaming, removing not used code).
Next few ones are preparation for new flow. The most important one
is "add VF representor one by one". It fully implements new flow.

New type of port representor (for subfunction) will be introduced in
follow up patchset.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  ice: reserve number of CP queues
  ice: adjust switchdev rebuild path
  ice: add VF representors one by one
  ice: realloc VSI stats arrays
  ice: set Tx topology every time new repr is added
  ice: allow changing SWITCHDEV_CTRL VSI queues
  ice: return pointer to representor
  ice: make representor code generic
  ice: remove VF pointer reference in eswitch code
  ice: track port representors in xarray
  ice: use repr instead of vf->repr
  ice: track q_id in representor
  ice: remove unused control VSI parameter
  ice: remove redundant max_vsi_num variable
  ice: rename switchdev to eswitch
