[lwip-users] [lwip] offloading lwip stack, again ! |

I was hoping that someone in the list will help me with this.
Having used lwip in unix simulation, i quite understand (but perhaps not as
many others in the list would) the way it uses the tap/tun device drivers to
communicate with the host native tcp/ip stack . Iam trying to extend this test
bench a bit further - make lwip as an *offloaded* stack on a linux or freebsd
system. I want to modify the socket layer in linux or freebsd to bypass their
native stack and exchange data directly with the tap/tun device, so that lwip
appears as an tcp offloaded stack. The changes in the socket layer should not
affect existing applications on the linux or freebsd.
The existing applications on linux/freebsd would now use the lwip stack
Can someone tell me if this is possible ? If so, I would like to know, how
coupled is the socket layer in the freebsd/linux system with its native tcpip
stack and which os would be better to use.
Thanks !
Ganesh
