Hi,
Sorry that I haven't given instruction how to use persistent port
with the new patch.
To use persistent port, the commands are as follows:
ipvsadm -A -t <VIP>:<port> [-s <scheduler>] -p
ipvsadm -a -t <VIP>:<port> -R <real server> ...
...
If the virtual service port is set persistent, connections
from the same clients are gauranteed to direct to the same
server. When a client sends request for the service at the
first time, the load balancer (director) selects a server
by the scheduling method and creates a connection and the
template. Then, the following connections from the same
client will be forwarded to the same server according to the
template in the specified time.

The source address of an incoming packet is used to lookup
connection template.

Sorry that I don't understand your question.
