On the new hardware platform, the configuration register space

	Update the comment of the live migration configuration scheme.

Change v5 -> v6
	Update VF device properties

Change v4 -> v5
	Remove BAR length alignment

Change v3 -> v4
	Rebase on kernel 6.15

Change v2 -> v3
	Put the changes of Pre_Copy into another bugfix patchset.

Change v1 -> v2
	Delete the vf_qm_state read operation in Pre_Copy

Longfang Liu (3):
  migration: update BAR space size
  migration: qm updates BAR configuration
  migration: adapt to new migration configuration
