Hi Timothy, I responded to your feedback before I started on RFCv3.. and took your silence as approval :).. I guess that email got lost in your inbox sea some where.. so re-posting the responses. So, this time, I will wait for your ack before I proceed to RFCv4.. Although.. after all these reviews.. I may just submit it as PATCHv1.. since the patch is almost there and there are no major objections any more.. Regards, Vish On 17 December 2014 at 23:59, Timothy B.

Almost there... just a few nits left.

...ticed TCP_RR on 1 vcpu 1 queue guest. - CPU utilization is increased in some cases. - All other cases, tx interrupts can perform equal or better than orphaning (much more obvious when testing small packet transmission as a byproduct since socket accounting works for TCP packet). Changes from RFCv4: - fix the virtqueue_enable_cb_delayed() return value when only 1 buffer is pending. - try to disable callbacks by publish event index in virtqueue_disable_cb(). Tests shows about 2% - 3% improvement on multiple sessions of TCP_RR. - Revert some of Micahel's tweaks from RFC v1 (see patch...
