[ovs-dev] STT Implementation Thoughts

[Simon Horman]

Hi Jesse, Hi all,

I am currently investigating how STT[1] may be implemented for Open vSwtich.
In the course of this it has struck me that a property particular
to STT is that it uses the TCP IP protocol number but actually isn't TCP.
Which makes me wonder how the receive-side it may be hooked into the Linux
kernel.

My thought so far is that some modifications may need to be made to
tcp_v4_rcv() and/or tcp_v6_rcv() to skip TCP processing of packets
for sockets that have been bound by STT. But I was wondering if you
have any thoughts on this.

I suspect that this is a conversation best had on the netdev list,
but I thought I would ask here first.
