mcs7830_set_reg() and mcs7830_get_reg() are called with buffers
from stack which must not be used directly for USB transfers.
This causes corruption of the stack particulary on non x86
architectures because DMA may be used for these transfers.

Improve usbnet's devdbg to always type-check diagnostic arguments,
like dev_dbg (device.h). This makes no change to the resulting size of
usbnet modules.
This patch also removes an #ifdef DEBUG directive from rndis_wlan so
it's devdbg statements are always type-checked at compile time.

The previous fix to paged packets broke the merging because it
reset the skb->len before we added it to the merged packet. This
wasn't detected because it simply resulted in the truncation of
the packet while the missing bit is subsequently retransmitted.
The fix is to store skb->len before we clobber it.

When running modprobe rt73usb, and then rmmod rt73usb, and then
iwconfig, the wlan0 device does not disappear. When repeating this
process again, we get a kernel Oops errors and "BUG: unable to handle
kernel paging request..." message in the kernel log.
The reason for this is that there is an error in rt2x00rfkill_free(),
which is called in the process of removing the device
(rt2x00lib_remove_dev() in rt2x00dev.c).
rt2x00rfkill_free() clears the RFKILL_STATE_ALLOCATED bit , which is
bit number 1 () in rt2x00dev->flags instead of in
rt2x00dev->rfkill_state. As a result, when checking the
DEVICE_STATE_REGISTERED_HW bit (bit number 1 in rt2x00dev->flags) in
rt2x00lib_remove_hw() it is **unset**, and we wrongly **don't** call
ieee80211_unregister_hw().
This patch corrects this: the parameter for __test_and_clear_bit() in
rt2x00rfkill_free() should be &rt2x00dev->rfkill_state and not
&rt2x00dev->flags.

The country IE number of channels on 5 GHz specifies the number
of 5 GHz channels, not the number of sequential channel numbers.
For example, if in a country IEs if the first channel given is 36
and the number of channels passed is 4 then the individual channel
numbers defined for the 5 GHz PHY by these parameters
are: 36, 40, 44, 48
not: 36, 37, 38, 39

This fixes a regression on disallowing bands introduced with the new
802.11d support. The issue is that IEEE-802.11 allows APs to send
a subset of what a country regulatory domain defines. This was clarified
in this document:
http://tinyurl.com/11d-clarification
As such it is possible, and this is what is done in practice, that a
single band 2.4 GHz AP will only send 2.4 GHz band regulatory information
through the 802.11 country information element and then the current
intersection with what CRDA provided yields a regulatory domain with
no 5 GHz information -- even though that country may actually allow
5 GHz operation. We correct this by only applying the intersection rules
on a channel if the the intersection yields a regulatory rule on the
same band the channel is on.

In function iwl_send_cmd_sync(), if the flag CMD_WANT_SKB is set but
we are not provided with a valid SKB (cmd->meta.u.skb == NULL), we need
to remove the CMD_WANT_SKB flag from the TX cmd queue. Otherwise in case
the cmd comes in later, it will possibly set an invalid address. Thus
it causes an invalid memory access.
This fixed the bug http://bugzilla.kernel.org/show_bug.cgi?id=11326.

This was not supposed to be a bitwise AND operation, but a check of
two separate conditions. Anyway, the old code happened to result in
the same behavior, so this is just changing the code to be easier to
understand and also to keep sparse from warning about dubious
operators.

Data structures that come over the wire from the WLAN firmware must be packed.
This fixes alignment problems on the blackfin architecture and, reportedly, on
the AVR32.
This is a replacement for the previous version of this patch which had also
explicitly used get_unaligned_ macros. As Johannes Berg pointed out, these
macros were unnecessary.

Roel Kluin reported a bug in two error paths where skbs were wrongly
being freed using kfree(). He provided a fix where it was replaced to
kfree_skb(), as it should be.
However, in i2400mu_rx(), the error path was missing returning an
indication of the failure. Changed to reset rx_skb to NULL and return
it to the caller, i2400mu_rxd(). It will be treated as a transient
error and just ignore the packet.
Depending on the buffering conditions inside the device, the data
packet might be dropped or the device will signal the host again for
data-ready-to-read and the host will retry.

Contrary to what the docs say, the 'extended interrupt cause' bit in
the interrupt cause register (bit 1) appears to not be maskable on at
least some of the mv643xx_eth platforms, making writing zeroes to the
interrupt mask register but not the extended interrupt mask register
insufficient to stop interrupts from occuring. Therefore, also write
zeroes to the extended interrupt mask register when shutting down the
port.
This fixes the interrupt storm seen on the Pegasos board when shutting
down the interface.

Commit 66e63ffbc04706568d8789cbb00eaa8ddbcae648 ("mv643xx_eth:
implement ->set_rx_mode()") cleaned up mv643xx_eth's multicast filter
programming, but broke it as well.
The non-special multicast filter table (for multicast addresses that
are not of the form 01:00:5e:00:00:xx) consists of 256 hash table
buckets organised as 64 32-bit words, where the 'accept' bits are
in the LSB of each byte, so in bits 24 16 8 0 of each 32-bit word.
The old code got this right, but the referenced commit broke this by
using bits 3 2 1 0 instead. This commit fixes this up.

On the Pegasos board, we can't do DMA burst that are longer than
one cache line. For now, go back to using 32 byte DMA bursts for
all mv643xx_eth platforms -- we can switch the ARM-based platforms
back to doing long 128 byte bursts in the next development cycle.

The trick in socket splicing where we try to convert the skb->data
into a page based reference using virt_to_page() does not work so
well.
The idea is to pass the virt_to_page() reference via the pipe
buffer, and refcount the buffer using a SKB reference.
But if we are splicing from a socket to a socket (via sendpage)
this doesn't work.
The from side processing will grab the page (and SKB) references.
The sendpage() calls will grab page references only, return, and
then the from side processing completes and drops the SKB ref.
The page based reference to skb->data is not enough to keep the
kmalloc() buffer backing it from being reused. Yet, that is
all that the socket send side has at this point.
This leads to data corruption if the skb->data buffer is reused
by SLAB before the send side socket actually gets the TX packet
out to the device.
The fix employed here is to simply allocate a page and copy the
skb->data bytes into that page.
This will hurt performance, but there is no clear way to fix this
properly without a copy at the present time, and it is important
to get rid of the data corruption.
With fixes from Herbert Xu.

This patch modifies how the tg3 driver handles device firmware.
The patch starts by consolidating David Woodhouse's earlier patch under
the same name. Specifically, the patch moves the request_firmware call
into a separate tg3_request_firmware() function and calls that function
from tg3_open() rather than tg3_init_one().
The patch then goes on to limit the number of devices that will make
request_firmware calls. The original firmware patch unnecessarily
requested TSO firmware for devices that did not need it. This patch
reduces the set of devices making TSO firmware patches to approximately
the following device set : 5703, 5704, and 5705.
Finally, the patch reduces the effects of a request_firmware() failure.
For those devices that are requesting TSO firmware, the driver will turn
off the TSO capability. If TSO firmware becomes available at a later
time, the device can be closed and then opened again to reacquire the
TSO capability.

netif_carrier_off() is sufficient to stop Tx into the driver. Stopping the Tx
queues is redundant and unnecessary. By the same token, netif_carrier_on()
will be sufficient to re-enable Tx, so waking the queues is unnecessary.

Register VLAN ID 0 so that frames with VLAN ID 0 are received and get
their tag stripped when ixgbe is not in DCB mode. VLAN ID 0 means
that the frame is 'priority tagged' only - it is not a VLAN, but the
priority value is the tag in valid. The functions
ixgbe_vlan_rx_register() and ixgbe_vlan_rx_kill_vid() were moved up a
couple functions to correct compiling issues with this change.

The is an issue where setting Relaxed Ordering (RO) bit
(in a PCI-E write transaction) on 82598 causing the chipset
to drop DCA hints. This patch forces RO not to be set for
descriptors as well as payload. This will only be in effect
while DCA is enabled and no performance difference was
noticed in testing.

I'm trying to track down why people're hitting the checksum warning
in skb_gso_segment. As the problem seems to be hitting lots of
people and I can't reproduce it or locate the bug, here is a patch
to print out more details which hopefully should help us to track
this down.

As the assigned value is being overwritten shortly after, it can be

This is copy and paste from the original driver. As skb_reserve() is
also called within korina_alloc_ring() when initially allocating the
receive descriptors, the same should be done when allocating new space
after passing an skb to upper layers.

After the last loop iteration, i has the value RC32434_NUM_RDS and
therefore leads to an index overflow when used afterwards to address the
last element. This is yet another another bug introduced when rewriting
parts of the driver for upstream preparation, as the original driver
used 'RC32434_NUM_RDS - 1' instead.

The lro manager's frag_align_pad setting was missing,
leading to misaligned access to the skb passed up

In rare cases when an underrun occur, all macb buffers where consumed
and the netif_queue was stopped infinitely. This happens then the TGO
(transfer ongoing) bit in the TSR is set (and UND). It seems like
clening up after the underrun makes the driver and the macb hardware
end up in an inconsistent state. The result of this is that in the
following calls to macb_tx no TX buffers are released -> the
netif_queue was stopped, and never woken up again.
The solution is to disable the transmitter, if TGO is set, before
clening up after the underrun, and re-enable the transmitter when the
cleaning up is done.
