Subject: Re: [PATCH net-next] xen-netfront: try linearizing SKB if it occupies
 too many slots

Hi,

Yes, it lost traction recently a little bit. The latest idea is to use 
the skb segmenting code in netfront to slice up the skb until it becomes 
a set of skbs which can fit through the ring. But to test that out I 
need to make pktgen work with TCP, that's where this got stopped.
