Don't do the num_tx_queues based masking on calculating tx queue

1) num_tx_queues is not always power-of-2, because it also depends on

on a 6 cpu system.
2) queue_mapping will be limited by real_num_tx_queues=num_tx_queues

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().

This patch adds a possibility for PHY drivers to provide

port in a multi-PHY device) generated an interrupt. This
function is called in phy_change() as phy_change() shouldn't

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.

This patch does two things:
1) On 82599, the PHY is emedded in the MAC. On 82598, the SFP+ NIC has an external PHY. The reset in the SFP+ setup patch for 82598 is unnecessary on 82599, and adds extra dead time to device initialization. This removes that PHY reset for 82599 only.
2) On 82599, the SFP+ modules are multispeed fiber modules (10G/1G). We need to make sure to identify them properly for the remaining init sections to properly set them up.

If the thread calling dm_kcopyd_copy is delayed due to scheduling inside
split_job/segment_complete and the subjobs complete before the loop in
split_job completes, the kcopyd callback could be invoked from the
thread that called dm_kcopyd_copy instead of the kcopyd workqueue.
dm_kcopyd_copy -> split_job -> segment_complete -> job->fn()
Snapshots depend on the fact that callbacks are called from the singlethreaded
kcopyd workqueue and expect that there is no racing between individual
callbacks. The racing between callbacks can lead to corruption of exception
store and it can also mean that exception store callbacks are called twice
for the same exception - a likely reason for crashes reported inside
pending_complete() / remove_exception().
This patch fixes two problems:
1. job->fn being called from the thread that submitted the job (see above).
- Fix: hand over the completion callback to the kcopyd thread.
2. job->fn(read_err, write_err, job->context); in segment_complete
reports the error of the last subjob, not the union of all errors.
- Fix: pass job->write_err to the callback to report all error bits
(it is done already in run_complete_job)

Use a variable in segment_complete() to point to the dm_kcopyd_client
struct and only release job->pages in run_complete_job() if any are
defined. These changes are needed by the next patch.

Barriers are submitted to a worker thread that issues them in-order.
The thread is modified so that when it sees a barrier request it waits
for all pending IO before the request then submits the barrier and
waits for it. (We must wait, otherwise it could be intermixed with
following requests.)
Errors from the barrier request are recorded in a per-device barrier_error
variable. There may be only one barrier request in progress at once.
For now, the barrier request is converted to a non-barrier request when
sending it to the underlying device.
This patch guarantees correct barrier behavior if the underlying device
doesn't perform write-back caching. The same requirement existed before
barriers were supported in dm.
Bottom layer barrier support (sending barriers by target drivers) and
handling devices with write-back caches will be done in further patches.

Remove queue_io return value and a loop in dm_request.
IO may be submitted to a worker thread with queue_io(). queue_io() sets
DMF_QUEUE_IO_TO_THREAD so that all further IO is queued for the thread. When
the thread finishes its work, it clears DMF_QUEUE_IO_TO_THREAD and from this
point on, requests are submitted from dm_request again. This will be used
for processing barriers.
Remove the loop in dm_request. queue_io() can submit I/Os to the worker thread
even if DMF_QUEUE_IO_TO_THREAD was not set.

Split the DMF_BLOCK_IO flag into two.
DMF_BLOCK_IO_FOR_SUSPEND is set when I/O must be blocked while suspending a
device. DMF_QUEUE_IO_TO_THREAD is set when I/O must be queued to a
worker thread for later processing.

This patch provides support for data integrity passthrough in the device
mapper.

profile is preallocated for the DM device.
- If all component devices have compatible profiles the DM device is
flagged as capable.
- Handle integrity metadata when splitting and cloning bios.

This patch removes the sysfs entry num_vfs which was added to support
enabling pci virtual functions for 82576.
To prevent VFs from loading automatically a module parameter "max_vfs" was
added so that the number of VFs per PF can be limited. This is especially
useful when 4 or more 82576 ports are on the system because otherwise to
load all VFs would result in 8 interface per physical port.

This adds an igbvf driver to handle virtual functions provided by the
igb driver when SR-IOV has been enabled. A virtual function is a
lightweight pci-e function that supports a single queue and shares
resources with the 82576 physical function contained within the igb
driver.
To spawn virtual functions from the igb driver all that is needed is to
enable CONFIG_PCI_IOV and have an 82576 Ethernet adapter on a system that
supports SR-IOV in the BIOS. The virtual functions will appear after the
interface is loaded.
