Code was clearly wrong, plus callers expect the mode change to happen as
soon as possible, not dropped on the floor until the next time some
other config value changes and a commit happens.

p54spi_op_tx needs to be called from different locking contexts.
Therefore we have to protect the linked list with irqsave spinlocks.

Michael Buesch cf68636a97 b43: Refresh RX poison on buffer recycling
The RX buffer poison needs to be refreshed, if we recycle an RX buffer,

Michael Buesch ec9a1d8c13 b43: Poison RX buffers
This patch adds poisoning and sanity checking to the RX DMA buffers.
This is used for protection against buggy hardware/firmware that raises
RX interrupts without doing an actual DMA transfer.

This mechanism protects against rare "bad packets" (due to uninitialized skb data)
and rare kernel crashes due to uninitialized RX headers.

The poison is selected to not match on valid frames and to be cheap for checking.

The poison check mechanism _might_ trigger incorrectly, if we are voluntarily
receiving frames with bad PLCP headers. However, this is nonfatal, because the
chance of such a match is basically zero and in case it happens it just results
in dropping the packet.
Bad-PLCP RX defaults to off, and you should leave it off unless you want to listen
to the latest news broadcasted by your microwave oven.

This patch also moves the initialization of the RX-header "length" field in front of
the mapping of the DMA buffer. The CPU should not touch the buffer after we mapped it.

Wu Fengguang 95615d90a3 ixgbe: fix tx queue index
Don't do the num_tx_queues based masking on calculating tx queue
index.

 1) num_tx_queues is not always power-of-2, because it also depends on
    the online cpu numbers. So the masking could be a performance bug
    on a 6 cpu system.
 2) queue_mapping will be limited by real_num_tx_queues=num_tx_queues
    in the generic netdev function set_cur_queue_map(). So the bound
    limiting here is not necessary.

This should be harmless - these macros always use little-endian

unchanged - but it is obviously wrong.

Michal Schmidt d119b39279 skge: fix occasional BUG during MTU change
The BUG_ON(skge->tx_ring.to_use != skge->tx_ring.to_clean) in skge_up()
was sometimes observed when setting MTU.

skge_down() disables the TX queue, but then reenables it by mistake via
skge_tx_clean().
Fix it by moving the waking of the queue from skge_tx_clean() to the
other caller. And to make sure start_xmit is not in progress on another
CPU, skge_down() should call netif_tx_disable().

The bug was reported to me by Jiri Jilek whose Debian system sometimes
failed to boot. He tested the patch and the bug did not happen anymore.

port in a multi-PHY device) generated an interrupt. This
function is called in phy_change() as phy_change() shouldn't
proceed if it is invoked for a PHY which didn't cause an
interrupt. So check for interrupt originator in phy_change()
to allow early-out.

James Bottomley 0d489ffb76 tg3: fix big endian MAC address collection failure
We noticed on parisc that our broadcoms all swapped MAC addresses going
from 2.6.29 to 2.6.30-rc1:

Apr 11 07:48:24 ion kernel: eth0: Tigon3 [partno(BCM95700A6) rev 0105] (PCI:66MHz:64-bit) MAC address 00:30:6e:4b:15:59
Apr 13 07:34:34 ion kernel: eth0: Tigon3 [partno(BCM95700A6) rev 0105] (PCI:66MHz:64-bit) MAC address 00:00:59:15:4b:6e

The problem patch is:

commit 6d348f2c1e
Author: Matt Carlson <mcarlson@broadcom.com>
Date:   Wed Feb 25 14:25:52 2009 +0000

    tg3: Eliminate tg3_nvram_read_swab()

With the root cause being the use of memcpy to set the mac address:

   memcpy(&dev->dev_addr[0], ((char *)&hi) + 2, 2);
   memcpy(&dev->dev_addr[2], (char *)&lo, sizeof(lo));

This might work on little endian machines, but it can't on big endian
ones.  You have to use the original setting mechanism to be correct on
all architectures.

The attached patch fixes parisc.

Brian Haley 5a31bec014 Bonding: fix zero address hole bug in arp_ip_target list
Fix a zero address hole bug in the bonding arp_ip_target list
that was causing the bond to ignore ARP replies (bugz 13006).
Instead of just setting the array entry to zero, we now
copy any additional entries down one slot, putting the
zero entry at the end.  With this change we can now have
all the loops that walk the array stop when they hit a zero
since there will be no addresses after it.

Changes are based in part on code fragment provided in kernel:

Alexander Duyck 9ca046d574 igb: do not check for vf_data if we didn't enable vfs
The driver is currently dumping a message in the log about failing to
allocate vf data when max_vfs is equal to 0.  This change makes it so the
error message is only displayed if we set max_vfs to a non zero value.

Alexander Duyck 2d16577106 igbvf: fix unused external references
The igbvbf driver exposed several unused extrnal references due to the fact
that code was copied from igb and then some functionality was removed.
This changes that so that unused functions are either removed or made
static.
