[PATCH 43/98] netfilter: xt_LOG: fix mark logging for IPv6 packets

[Luis Henriques]

3.5.7.17 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: =?UTF-8?q?Michal=20Kube=C4=8Dek?= <mkubecek@xxxxxxx>

commit d660164d79b67f879db35a7d61e47d3b99bc714e upstream.

In dump_ipv6_packet(), the "recurse" parameter is zero only if
dumping contents of a packet embedded into an ICMPv6 error
message. Therefore we want to log packet mark if recurse is
non-zero, not when it is zero.
