No, but there are moves to create a new netchannel2 protocol which will be more extensible, better documented and better able to support new hardware features like multiple receive queues. Of course it will allow us also to drop support for rx flip. The likelihood, however, is that we will continue to support it as a new plug-in datapath in the existing netfront/netback drivers, and negotiation will be required to use it. So we will basically continue to support rx-flip as a fallback option for the foreseeable future. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
