One struct will have fwmark added:
* ip_vs_conn
ip_vs_conn_new() and ip_vs_find_dest()
will have an extra param - fwmark
The effects of that, is in this patch.
*v3
regeneration of patch due to adding Simons
"IPVS: Add persistence engine to connection entry"
*v2
Simplified the patch according to Julians comments
Removed fwmark from ip_vs_conn_param,
and add fwmark to ip_vs_conn_new()
*v1
Two structs will have fwmark added:
* ip_vs_conn
* ip_vs_conn_param
