Xen users - May 2009 - VMDQ / netchannel2 support?

Hello,

Did 3.4 come with vmdq, sr-iov, etc.. (netchannel2) support included? If so,
is there any documentation available on how to make use of it?

Also, these techniques seem like a good way to improve network performance
on hardware that supports it, but for folks that want to use iptables and
other network management utilities from dom0, will it even be possible
anymore since the NICs seem to go straight to domU?

No, it is not released yet. You have to build the development trees from
http://xenbits.xensource.com/ext/netchannel2/ if you want to try any of this.

At the moment you cannot do packet filtering when directly assigning VF or VMQ
to the guest as packet go directly to guest memory.
