Hi, Cheng Xu
After modify qp to RTS, is that means this TCP stream is offloaded
to the hardware, and the inbound TCP segments related to the TCP stream
will not be received in the kernel stack where this driver is running.
If yes, the ACK of mpa reply will never been revieced by the stack?
Actually, this depends on our infrastructure. ERDMA collaborates with
OVS module, which indeed decides the direction of packets. It makes sure
that packet from VM will be sent to VM, and packet from RDMA will be
sent to RDMA engine. So, the ACK from VM will always be sent to VM.
Thanks,
Cheng Xu
OK, thanks for your explanation :)
