netfilter: nf_conntrack_reasm: properly handle packets fragmented into a single fragment
When an ICMPV6_PKT_TOOBIG message is received with a MTU below 1280,
all further packets include a fragment header.
Unlike regular defragmentation, conntrack also needs to "reassemble"
those fragments in order to obtain a packet without the fragment
header for connection tracking. Currently nf_conntrack_reasm checks
whether a fragment has either IP6_MF set or an offset != 0, which
makes it ignore those fragments.
Remove the invalid check and make reassembly handle fragment queues
containing only a single fragment.

netfilter: ctnetlink: fix creation of conntrack with helpers
This patch fixes a bug that triggers an assertion if you create
a conntrack entry with a helper and netfilter debugging is enabled.
Basically, we hit the assertion because the confirmation flag is
set before the conntrack extensions are added. To fix this, we
move the extension addition before the aforementioned flag is
set.
This patch also removes the possibility of setting a helper for
existing conntracks. This operation would also trigger the
assertion since we are not allowed to add new extensions for
existing conntracks. We know noone that could benefit from
this operation sanely.
Thanks to Eric Dumazet for initial posting a preliminary patch

Traffic (tcp) doesnot start on a vlan interface when gro is enabled.
Even the tcp handshake was not taking place.
This is because, the eth_type_trans call before the netif_receive_skb
in napi_gro_finish() resets the skb->dev to napi->dev from the previously
set vlan netdev interface. This causes the ip_route_input to drop the
incoming packet considering it as a packet coming from a martian source.
I could repro this on 2.6.32.7 (stable) and 2.6.33-rc7.

ipg: Remove device claimed by dl2k from pci id table
This patch removes D-Link DGE-550T PCI ID (1186:4000) from the ipg
driver. The ipg driver is for IP2000-based cards and the DGE-550T is
a DL2000-based card. The driver loads and works for a few moments, but
once a real workload is applied it stops operating. The ipg driver
claimed this ID since it was introduced in 2.6.24 and it's forced many
users to blacklist it.
The correct driver for this hardware is the dl2k driver, which has been
claiming this PCI ID since the 2.4 days.

percpu: add __percpu sparse annotations to net drivers
Add __percpu sparse annotations to net drivers.
These annotations are to make sparse consider percpu variables to be
in a different address space and warn if accessed without going
through percpu accessors. This patch doesn't affect normal builds.

The macro and type tricks around snmp stats make things a bit
interesting. DEFINE/DECLARE_SNMP_STAT() macros mark the target field
as __percpu and SNMP_UPD_PO_STATS() macro is updated accordingly. All
snmp_mib_*() users which used to cast the argument to (void **) are
updated to cast it to (void __percpu **).
