Re: TCP/IP stack for DPDK

hi,


netdp stack use rte_mbuf directly, so no packet copied from DPDK port queue to netdp stack. netdp forwarding performance is same as FreeBSD.

I have porting major FreeBSD tcp/ip stack to dpdk. new tcp/ip stack is based 
on dpdk rte_mbuf, rte_ring, rte_memory and rte_table. it is faster to 
forwarding packets.

Hello,

This is awesome work to be doing and badly needed to use DPDK for any L4 
purposes where it is very limited. I'll be following your progress.

You didn't mention your name, and compare your work with 
https://github.com/rumpkernel/dpdk-rumptcpip/ , and talk about behavior / 
performance, and how long you think it'll take. I'm curious if you can give 
some more comments.

I'm implementing an RX-side very basic stack myself... but I'm not using BSD 
standard APIs or doing TX-side like yours will have.

Matthew.
