Subject: [37/44] ipv6: conntrack: Add member of user to nf_ct_frag6_queue structure

2.6.27-stable review patch.  If anyone has any objections, please let us know.

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

From: Shan Wei <shanwei@...fujitsu.com>

commit c92b544bd5d8e7ed7d81c77bbecab6df2a95aa53 upstream.

The commit 0b5ccb2(title:ipv6: reassembly: use seperate reassembly queues for
conntrack and local delivery) has broken the saddr&&daddr member of
nf_ct_frag6_queue when creating new queue.  And then hash value
generated by nf_hashfn() was not equal with that generated by fq_find().
So, a new received fragment can't be inserted to right queue.

The patch fixes the bug with adding member of user to nf_ct_frag6_queue structure.
