Sorry, the previous post was not the new patch. Here it is:

Subject: [patch v2.2 04/12] IPVS: Add struct ip_vs_conn_param
Signed-off-by: Simon Horman <horms@xxxxxxxxxxxx>
---
The motivation for this is to allow persistence engine modules to
fill in the parameters.
v0.3
* Add missing changes to ip_vs_ftp.c
v2
* make "union nf_inet_addr fwmark" const
* Update for the recent addition of ip_vs_nfct.c
v2.2
* As suggested by Julian Anastasov
- Correct logic for inverse case in ip_vs_conn_fill_param_proto()
and ah_esp_conn_fill_param_proto()
- Update ip_vs_conn_out_get()'s comments as its parameters have changed
- Add missing call to ip_vs_conn_fill_param() before the second
invocation of ip_vs_conn_new() in ip_vs_sched_persist()
