This is v2 of:
https://listman.redhat.com/archives/libvir-list/2021-August/msg00187.html

Changes since v1 (suggested by Peter):
* split of the patch containing api and virsh adjustments into separate
  patches
* change of documentation (which I forgot to do before)

Kristina Hanicova (4):
  conf: propagate xmlDocPtr and flags into virInterfaceDefParseXML()
  api: add virInterfaceDefineFlags
  virsh: add support for '--validate' option in define interface
  interface_conf: add validation against schema in define
