[Qemu-devel] [PATCH RFC 0/3] qemu/vhost-net: mergeable buffers support

[Michael S. Tsirkin]

This adds mergeable buffers support in vhost-net in qemu.
With this patch, sending raw packets while vhost-net is active should
work as well: important for migration.  Compile-tested only for now.
David, could you please review and maybe try this out?
The kernel side is in vhost-net-next. I intend for it to got into
net-next and then into 2.6.36.

TODO: basic test. migration test, send pull request.

Michael S. Tsirkin (3):
  tap: generalize code for different vnet header len
  tap: add APIs for vnet header length
