Adds support for specifying a range of queues instead of a single queue
id. Flows will be distributed across the given range.
This is useful for multicore systems: Instead of having a single
application read packets from a queue, start multiple
instances on queues x, x+1, .. x+n. Each instance can process
flows independently.
Packets for the same connection are put into the same queue.
netfilter: conntrack: replace notify chain by function pointer
This patch removes the notify chain infrastructure and replace it
by a simple function pointer. This issue has been mentioned in the
mailing list several times: the use of the notify chain adds
too much overhead for something that is only used by ctnetlink.
This patch also changes nfnetlink_send(). It seems that gfp_any()
returns GFP_KERNEL for user-context request, like those via
ctnetlink, inside the RCU read-side section which is not valid.
Using GFP_KERNEL is also evil since netlink may schedule(),
this leads to "scheduling while atomic" bug reports.

netfilter: conntrack: simplify event caching system
This patch simplifies the conntrack event caching system by removing
several events:
* IPCT_[*]_VOLATILE, IPCT_HELPINFO and IPCT_NATINFO has been deleted
since the have no clients.
* IPCT_COUNTER_FILLING which is a leftover of the 32-bits counter
days.
* IPCT_REFRESH which is not of any use since we always include the
timeout in the messages.
After this patch, the existing events are:
* IPCT_NEW, IPCT_RELATED and IPCT_DESTROY, that are used to identify
addition and deletion of entries.
* IPCT_STATUS, that notes that the status bits have changes,
eg. IPS_SEEN_REPLY and IPS_ASSURED.
* IPCT_PROTOINFO, that reports that internal protocol information has
changed, eg. the TCP, DCCP and SCTP protocol state.
* IPCT_HELPER, that a helper has been assigned or unassigned to this
entry.
* IPCT_MARK and IPCT_SECMARK, that reports that the mark has changed, this
covers the case when a mark is set to zero.
* IPCT_NATSEQADJ, to report that there's updates in the NAT sequence
adjustment.

netfilter: nfnetlink: cleanup for nfnetlink_rcv_msg() function
This patch cleans up the message handling path in two aspects:

Netlink/nfnetlink headers. No need to check for the padding room.
* it removes a redundant header size checking that has been

netfilter: nf_ct_tcp: TCP simultaneous open support
The patch below adds supporting TCP simultaneous open to conntrack. The
unused LISTEN state is replaced by a new state (SYN_SENT2) denoting the
second SYN sent from the reply direction in the new case. The state table
is updated and the function tcp_in_window is modified to handle
simultaneous open.
The functionality can fairly easily be tested by socat. A sample tcpdump
recording
The RST packet was dropped in the raw table, thus it did not reach
conntrack. nfnetlink_conntrack is unpatched so it shows the new SYN_SENT2
state as the old unused LISTEN.
With TCP simultaneous open support we satisfy REQ-2 in RFC 5382 ;-) .
Additional minor correction in this patch is that in order to catch
uninitialized reply directions, "td_maxwin == 0" is used instead of
"td_end == 0" because the former can't be true except in uninitialized
state while td_end may accidentally be equal to zero in the mid of a
connection.

igb: Record host memory receive overflow in net_stats
Based on previous patch from Jesper Dangaard Brouer.
The RNBC (Receive No Buffers Count) register for the 82576, indicate
that frames were received when there were no available buffers in host
memory to store those frames (receive descriptor head and tail
pointers were equal). The packet is still received by the NIC if
there is space in the FIFO on the NIC.
As the RNBC value is not a packet drop, the driver stores this value
in net_stats.rx_fifo_errors to indicate that there were no system
buffers available for the incoming packet. Actual dropped packets
are counted in the MPC value.
Saving the stats in dev->net_stats makes it visible via
/proc/net/dev as "fifo", and thus viewable to ifconfig
as "overruns" and 'netstat -i' as "RX-OVR".
The Receive No Buffers Count (RNBC) can already be queried by
ethtool -S as "rx_no_buffer_count".

gianfar: fix BUG under load after introduction of skb recycling
Since commit 0fd56bb5be6455d0d42241e65aed057244665e5e ("gianfar:
Add support for skb recycling"), gianfar puts skbuffs that are in
the rx ring back onto the recycle list as-is in case there was a
receive error, but this breaks the following invariant: that all
skbuffs on the recycle list have skb->data = skb->head + NET_SKB_PAD.
The RXBUF_ALIGNMENT realignment done in gfar_new_skb() will be done
twice on skbuffs recycled in this way, causing there not to be enough
room in the skb anymore to receive a full packet, eventually leading
to an skb_over_panic from gfar_clean_rx_ring() -> skb_put().
Resetting the skb->data pointer to skb->head + NET_SKB_PAD before
putting the skb back onto the recycle list restores the mentioned
invariant, and should fix this issue.

iwlcore: Allow skb allocation from tasklet.
If RX queue becomes empty then we need to restock the queue from tasklet to prevent
ucode from starving. A caller to iwl_rx_allocate will decide if allocated buffer should
come from GFP_ATOMIC or GFP_KERNEL.

iwlcore: support ICT interrupt
Add ICT interrupt handler support, ICT should improve CPU utilization
since it does not require target read which is very expensive. This
interrupt handler only added to 5000 cards and newer. Device will write
interrupts to ICT shared table to inform driver about its interrupts.
These patches will not touch 3945 and 4965 interrupt handlers and tasklet.

iwlwifi: support "pure 40MHz" in RXON command
Fix the bug when using 11n "pure 40MHz" mode cause uCode
crashing by adding support for "pure 40MHz" in RX_ON command flag.
the "mode" field (bits 25:26) has value of 0-3
0 = 20 MHz only
1 = 40MHz only
2 = Mixed
3 = Reserved
Control Channel ID (bit 22) is valid only in Mixed mode.

iwlcore: register locks
Add new lock to be used when accessing some registers. Also move
the register lock and iwl_grab_nic_access inside the function for register access. This
will prevent from forgetting to hold locks and nic access in the right way and make code
easier to maintain.
We over use the priv->lock spin lock and I guess we need to add new
one for Tx queue after that we might need to change most of these lock to
BH and just keep priv->lock as irq type.
