[PATCH v3 0/4] Enhance docs on virtio-user as KNI replacement

[Bruce Richardson]

Since use of KNI is no longer advised (due to known issues and the fact
it's an out-of-tree module), virtio-user is recommended for new
developments. To help encourage this, we improve the doc HOWTO section
on using virtio-user and add a link to that document from the main KNI
section in the programmers guide.

v3:
* Added two extra patches:
  - rename document files to match new section name
  - add note to KNI programmers guide section
* minor updates to patch 2, and added stable on CC for that patch

Bruce Richardson (4):
  doc/howto: rework section on virtio-user as exception path
  doc/howto: rename files to match new content name
  doc/howto: add code example to virtio-user exception path doc
  doc/prog_guide: add reference to virtio-user from KNI doc
