This series contains a variety of refactors and cleanups in the VF code for
the ice driver. Its primary focus is to cleanup a few areas of the driver
before we begin implementing Scalable IOV.

This includes some cleanup and simplification of the VF operations and
addition of a few new operations that will be required by Scalable IOV, as
well as some other refactors needed for the handling of VF subfunctions.

It also contains a patch for changing the way we handle the mapping of the
PCI BAR 0 registers to allow sparse maps. This is done to enable iRDMA to
map the RDMA registers with write combining. Today, the iRDMA driver tries
this, but since the ice driver already mapped them as uncachable, the write
combining does not take effect. This results in additional latency as the
write combining can't be used.

This is fixed by modifying the driver to perform its own iomaps to map the
region before the RDMA space and the region after the space separately. We
can't just reduce the size of the map because Scalable IOV will need the
registers in the region beyond the RDMA area.

Jacob Keller (13):
  ice: fix function comment referring to ice_vsi_alloc
  ice: drop unnecessary VF parameter from several VSI functions
  ice: move vsi_type assignment from ice_vsi_alloc to ice_vsi_cfg

  ice: Fix RDMA latency issue by allowing write-combining
  ice: move ice_vf_vsi_release into ice_vf_lib.c
  ice: Pull common tasks into ice_vf_post_vsi_rebuild
  ice: add a function to initialize vf entry
  ice: introduce ice_vf_init_host_cfg function
  ice: convert vf_ops .vsi_rebuild to .create_vsi
  ice: introduce clear_reset_state operation
  ice: introduce .irq_close VF operation
  ice: remove unnecessary virtchnl_ether_addr struct use
