[Qemu-devel] [PATCHv5 00/11] vhost-net: upstream integration

[Michael S. Tsirkin]

Here's a patchset with vhost support for upstream qemu,
rebased to latest bits, and with all comments I'm aware of
addressed.

Please consider for merging.  Anthony, if you are still deliberating
some issues, maybe the series can be merged partially?  This will at
least reduce the amount of noise from reposting the large patchset.

Changes from v4:
  address amit's style comments: mostly renaming for clarity

Changes from v3:
  vhost: vhost net support: use typedef instead of struct name
  virtio: add set_status callback: fix up non-PCI bindings

Changes from v2:
  Addressed style comments
  Detect mapping changes and abort
  Unmap ring on cleanup

Changes from v1:
  Addressed style comments
  Migration fixes.
  Gracefully fail with non-tap backends.
