rt2x00: Fix double usage of skb->cb in USB RX path.

It is not safe to use the skb->cb area for both the rxd and
skb_frame_desc data at the same time, while they occupy an overlapping
piece of memory. This can lead to hard to trace crashes as pointers

rt2x00: Centralize RX packet alignment handling in rt2x00lib.

When rt2x00pci will be switched over to dynamically mapped skb's
instead of statically allocated DMA buffers, it no longer can handle
alignment of RX packets in a copy step, and needs to implement the
same scheme as rt2x00usb does.

In order to make the patch on dynamically mapped skb's smaller,
already centralize the alignment handling into rt2x00lib. This allows
us to move more code in rt2x00lib, and thus remove code duplication

rt2x00: Don't kick TX queue after each frame

TX queues shouldn't be kicked after each frame that is put into the
queue.  This could cause problems during RTS and CTS-to-self as well
as with fragmentation. In all those cases you want all frames to be
send out in a single burst. Off course we shouldn't let the queue fill
up entirely, thus we introduce a 10% threshold which, when reached,
will force the frames to be send out regardless of the frame.

In addition we should prevent queues to become full in such a way
that the tx() handler can fail. Instead of stopping the queue when
it is full, we should stop it when it is below the threshold.

ipv6 netns: Address labels per namespace

This pacth makes IPv6 address labels per network namespace.
It keeps the global label tables, ip6addrlbl_table, but
adds a 'net' member to each ip6addrlbl_entry.
This new member is taken into account when matching labels.

Changelog
=========
* v1: Initial version
* v2:
  * Minize the penalty when network namespaces are not configured:
      *  the 'net' member is added only if CONFIG_NET_NS is
         defined. This saves space when network namespaces are not
         configured.
      * 'net' value is retrieved with the inlined function
         ip6addrlbl_net() that always return &init_net when
         CONFIG_NET_NS is not defined.
  * 'net' member in ip6addrlbl_entry renamed to the less generic
    'lbl_net' name (helps code search).

As far as I can see ctnetlink_del_conntrack() is used to destroy a
conntrack on behalf of the user. There is an sk_buff, but I don't think

tg3: Fix 5761 WOL

On 5761 non-e devices, two problems prevent the administrator from
overriding the WOL settings in the device's NVRAM.

The first problem is that GPIO 0 and GPIO 2 have been swapped.  This
change prevented the administrator from turning on WOL when it is
disabled in NVRAM.  The fix is to add a new path for the 5761 that
swaps the two GPIOs in the code as well.

The second problem is that GPIO 1 could not be toggled by the driver
because the GPIO is shared with the debug UART GPIO.  This will prevent
the administrator from being able to turn WOL off if it was enabled in
NVRAM.  The fix is to always disable the debug UART after a GRC reset.

"Fix supporting flowctrl code" introduced a bug that prevents 5714S,
5715S and 5780S devices from falling back to a forced link mode.  The
problem is that the added flow control check will always fail if flow
control is set to autoneg and either RX or TX (or both) flow control
is enabled.  The driver defaults to setting flow control to autoneg

This fixes an issus that made "iwconfig eth1 power on" non-working.
When we get a "PS sleep" event, we have to confirm this to the firmware.

tipc: Prevent access of non-existent field in short message header

This patch eliminates a case where TIPC's link code could try reading
a field that is not present in a short message header.  (The random
value obtained was not being used, but the read operation could result
in an invalid memory access exception in extremely rare circumstances.)

tipc: Minor optimizations to received message processing

This patch enhances TIPC's handler for incoming messages in two
ways:
- the trivial, single-use routine for processing non-sequenced
  messages has been merged into the main handler
- the interface that received a message is now identified without
  having to access and/or modify the associated sk_buff

tipc: Fix minor bugs in link session number handling

This patch introduces a new, out-of-range value to indicate that
a link endpoint does not have an existing session established
with its peer, eliminating the risk that the previously used
"invalid session number" value (i.e. zero) might eventually be
assigned as a valid session number and cause incorrect link
behavior.

The patch also introduces explicit bit masking when assigning a
new link session number to ensure it does not exceed 16 bits.

tipc: Fix bugs in message error code display when debugging

This patch corrects two problems in the display of error code
information in TIPC messages when debugging:
- no longer tries to display error code in NAME_DISTRIBUTOR
  messages, which don't have the error field
- now displays error code in 24 byte data messages, which do
  have the error field

tipc: Standardize error checking on incoming messages via native API

This patch re-orders & re-groups the error checks performed on
messages being delivered to native API ports, in order to clarify the
similarities and differences required for the various message types.

tipc: Fix bug in connection setup via native API

This patch fixes a bug that prevented TIPC from receiving a
connection setup request message on a native TIPC port.
The revised connection setup logic ensures that validation
of the source of a connection-based message is skipped if
the port is not yet connected to a peer.
