netfilter: ctnetlink: fix double helper assignation for NAT'ed conntracks
If we create a conntrack that has NAT handlings and a helper, the helper
is assigned twice. This happens because nf_nat_setup_info() - via
nf_conntrack_alter_reply() - sets the helper before ctnetlink, which
indeed does not check if the conntrack already has a helper as it thinks that
it is a brand new conntrack.
The fix moves the helper assignation before the set of the status flags.
This avoids a bogus assertion in __nf_ct_ext_add (if netfilter assertions are
enabled) which checks that the conntrack must not be confirmed.

dccp: Fix panic caused by too early termination of retransmission mechanism
Thanks is due to Wei Yongjun for the detailed analysis and description of this
bug at http://marc.info/?l=dccp&m=121739364909199&w=2
The problem is that invalid packets received by a client in state REQUEST cause
the retransmission timer for the DCCP-Request to be reset. This includes freeing
the Request-skb ( in dccp_rcv_request_sent_state_process() ). As a consequence,
* the arrival of further packets cause a double-free, triggering a panic(),
* the connection then may hang, since further retransmissions are blocked.
This patch changes the order of statements so that the retransmission timer is
reset, and the pending Request freed, only if a valid Response has arrived (or
the number of sysctl-retries has been exhausted).
Further changes:
----------------
To be on the safe side, replaced __kfree_skb with kfree_skb so that if due to
unexpected circumstances the sk_send_head is NULL the WARN_ON is used instead.

This bug revealed that not all firmware versions service driver events

We fix this by re-inserting the VLAN tag into the packet when necessary.

[netdrvr] uninline atl1e_setup_mac_ctrl()
There doesn't seem to be a compelling reason why atl1e_setup_mac_ctrl()

It's not used in any place where speed would matter much, and as long as
it has only one caller non-ancient gcc versions anyway inline it
automatically.

regression from 2.6.26 related to suspend, hibernation and

'ethtool -s eth0 wol g', the box hangs solid during all of these
operations, while executing either sky2_suspend(), or
sky2_shutdown(). This patch fixes it for me.
