[PATCH v2 0/3] Follow VirtIO initialization properly at vdpa net cvq isolation probing

Posted by Eugenio Pérez 7 months, 2 weeks ago

This series solves a few issues.  The most obvious is that the feature set was
done previous to ACKNOWLEDGE | DRIVER status bit set.  Current vdpa devices are
permissive with this, but it is better to follow the standard.

Apart from that it fixes two issues reported by Peter Maydell:
* Stop probing CVQ isolation if cannot set features (goto missed).
* Fix incorrect error message statis "error setting features", while it should
say status.

v2: add forgotten Fixes tag

Eugenio Pérez (3):
  vdpa net: fix error message setting virtio status
  vdpa net: stop probing if cannot set features
  vdpa net: follow VirtIO initialization properly at cvq isolation

QE tested this series with regression testing, everything works fine.
