====================
ice: cleanups and preparation for live migration

Jake Keller says:

Various cleanups and preparation to the ice driver code for supporting
SR-IOV live migration.

The logic for unpacking Rx queue context data is added. This is the inverse
of the existing packing logic. Thanks to <linux/packing.h> this is trivial
to add.

Code to enable both reading and writing the Tx queue context for a queue
over a shared hardware register interface is added. Thanks to ice_adapter,
this is locked across all PFs that need to use it, preventing concurrency
issues with multiple PFs.

The RSS hash configuration requested by a VF is cached within the VF
structure. This will be used to track and restore the same configuration
during migration load.

ice_sriov_set_msix_vec_count() is updated to use pci_iov_vf_id() instead of
open-coding a worse equivalent, and checks to avoid rebuilding MSI-X if the
current request is for the existing amount of vectors.

A new ice_get_vf_by_dev() helper function is added to simplify accessing a
VF from its PCI device structure. This will be used more heavily within the
live migration code itself.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  ice: introduce ice_get_vf_by_dev() wrapper
  ice: avoid rebuilding if MSI-X vector count is unchanged
  ice: use pci_iov_vf_id() to get VF ID
  ice: expose VF functions used by live migration
  ice: move ice_vsi_update_l2tsel to ice_lib.c
  ice: save RSS hash configuration for migration
  ice: add functions to get and set Tx queue context
  ice: add support for reading and unpacking Rx queue context
