Subject: [PATCH 1/8] IPVS: Backup, Prepare for transferring firewall marks (fwmark) to the backup daemon.
From: Hans Schillstrom <hans.schillstrom@...csson.com>
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.
