Subject: [PATCH 5/8] netfilter: nf_ct_pptp: fix DNATed PPTP connection address translation

From: Sanket Shah <sanket.shah@...tecore.com>

When both the server and the client are NATed, the set-link-info control
packet containing the peer's call-id field is not properly translated.

I have verified that it was working in 2.6.16.13 kernel previously but
due to rewrite, this scenario stopped working (Not knowing exact version
when it stopped working).
