Don Skidmore 19343de279 ixgbe: fix regression on some 82598 adapters
The change to check the SFP+ module again on open() was
causing the XFP (non-SFP+) adapters to be rejected. We
only want to try and re-identify the SFP+ module if the
original probe found that this device was an SFP+ device.
So for this code path (driver loaded with SFP module, module
inserted, ifconfig up of the device) the type will be
ixgbe_phy_unknown for an unidentified SFP+ module.  So we
only check if that is the case.

This problem also shows up on Copper devices.

Don Skidmore 63d6e1d80a ixgbe: fix issues with failing to detect insert of unsupported module
Several small fixes around negative test case of the insertion of a
IXGBE_ERR_NOT_SUPPORTED module.

- mdio45_probe call was always failing due to mdio.prtad not being
set.  The function set to mdio.mdio_read was still working as we just
happen to always be at prtad == 0.  This will allow us to set the phy_id
and phy.type correctly now.

- There was timing issue with i2c calls when initiated from a tasklet.
A small delay was added to allow the electrical oscillation to calm down.

- Logic change in ixgbe_sfp_task that allows NOT_SUPPORTED condition
to be recognized.

Ron Mercer 6a47330892 qlge: Add/use function for link up/down.
We need to set/clear the mac address register when the link goes up/down
respectively.  Without this both ports of a 2-port device can end up
with the same mac address in a bonding scenario.
The new ql_link_on() and ql_link_off() will also be used in handling
certain firmware events.

Ron Mercer 7fab3bfe08 qlge: Fix MAC address bonding issue.
This addes functionality to set/clear the MAC address in the hardware
when the link goes up/down.
The MAC address register is persistent across function resets. In
bonding the same address can bounce from one port to the other.  This
can cause packets to be delivered to the wrong port.
This patch clears the MAC address in the hardware when the link is down
and sets it when the link comes up.
It was found that pulling/pushing the cable from one port to another
causes the same MAC address to be in both ports.
The next patch in this series will use this functionality as well.

The hardware semaphore covers the configuration register as well as the
ICB registers.  The ICB high and low regs contain the address of the
initialization control block and the config register is used to signal
the hardware that a block is ready to be downloaded.  Currently we were
only protecting the ICB regs.  This changes expands to cover the config
register as well.

Wade Farnsworth 42caa07404 phylib: fixes for PHY_RESUMING state changes
The PHY_HALTED state disables phydev->link, but the link will not be
updated upon entering PHY_RESUMING.  Add a call to phy_read_status() to
update the link before entering PHY_RUNNING.  If the link is not up at
this point, enter the PHY_NOLINK state instead.

Also, when transitioning from PHY_RESUMING to PHY_RUNNING, calls to
netif_carrier_on() and phydev->adjust_link() are missing.  Add the calls
similar to the other transitions to PHY_RUNNING.

Dhananjay Phadke 67c38fc61a netxen: avoid frequent firmware reset
Restrict firmware reset to following cases -

o chip rev is NX2031 (firmare doesn't support heartbit).
o firmware is dead.
o previous attempt to init firmware had failed.
o we have got newer file firmware.

This speeds up module load tremendously (by upto 8 sec),
also avoids downtime for NCSI (management) pass-thru
traffic.

David S. Miller 11687a1099 Revert "veth: prevent oops caused by netdev destructor"
This reverts commit ae0e8e8220.

This change had two problems:

1) Since it frees the stats in the drivers' close method, we
   can OOPS in the transmit routine.

2) stats are no longer remembered across ifdown/ifup which
   disagrees with how every other device operates.

Thanks to analysis and test patch from Serge E. Hallyn
and initial OOPS report by Sachin Sant.

Ooiwa Naohiro 7959ea254e bnx2: Fix the behavior of ethtool when ONBOOT=no
I found a little bug.

When configure in ifcfg-eth* is ONBOOT=no,
the behavior of ethtool command is wrong.

    # grep ONBOOT /etc/sysconfig/network-scripts/ifcfg-eth2
    ONBOOT=no
    # ethtool eth2 | tail -n1
            Link detected: yes

I think "Link detected" should be "no".

Alan Cox a6540f731d ppp: Fix throttling bugs
The ppp layer goes around calling the unthrottle method from non sleeping
paths. This isn't safe because the unthrottle methods in the tty layer need
to be able to sleep (consider a USB dongle).

Until now this didn't show up because the ppp layer never actually throttled
a port so the unthrottle was always a no-op. Currently it's a mutex taking
path so warnings are spewed if the unthrottle occurs via certain paths.

Fix this by removing the unneccessary unthrottle calls.

Jouni Malinen f0214843ba ath9k: Fix PCI FATAL interrupts by restoring RETRY_TIMEOUT disabling
An earlier commit, 'ath9k: remove dummy PCI "retry timeout" fix', removed
code that was documented to disable RETRY_TIMEOUT register (PCI reg
0x41) since it was claimed to be a no-op. However, it turns out that
there are some combinations of hosts and ath9k-supported cards for
which this is not a no-op (reg 0x41 has value 0x80, not 0) and this
code (or something similar) is needed. In such cases, the driver may
be next to unusable due to very frequent PCI FATAL interrupts from the
card.

Reverting the earlier commit, i.e., restoring the RETRY_TIMEOUT
disabling, seems to resolve the issue. Since the removal of this code
was not based on any known issue and was purely a cleanup change, the
safest option here is to just revert that commit. Should there be
desire to clean this up in the future, the change will need to be
tested with a more complete coverage of cards and host systems.

Zhu Yi 4e9aa52e36 iwmc3200wifi: fix potential kernel oops on module removal
The iwm_if_free() is called before destroy_workqueue for isr_wq on
device remove method. But if there is still some pending work in
the isr_wq, the required data structures are already freed at this
point. This leeds a kernel oops. The patch fixes this problem by
moving iwm_if_free after destroy_workqueue.

Zhu Yi d7e057dca3 iwmc3200wifi: add iwm_if_add and iwm_if_remove
We used to do alloc_netdev and register_netdev at the same time in
iwm_if_alloc. But some bus related structures will only be initialized
after iwm_priv is allocated. This caused a race condition that the
netdev might be registered earlier. The patch adds iwm_if_add and
iwm_if_remove so that the bus layer could register the device after
all initialization is done.

Prabhanjan Sarnaik 6877f54e6a mv643xx_eth: fix unicast filter programming in promiscuous mode
The Unicast Promiscious Mode (UPM) bit in the mv643xx_eth port
configuration register doesn't do exactly what its name would suggest:
setting this bit merely enables reception of all unicast frames with a
destination address that differs from our local MAC address in bits
[47:4].  In particular, it doesn't have any effect on unicast frames
with a destination address that matches our MAC address in bits [47:4]
-- these will still be tested against the 16-entry unicast address
filter table.

Therefore, if the interface is set to promiscuous mode, just setting
the unicast promiscuous bit isn't enough -- we need to set all filter
bits in the unicast filter table to 1 as well.

Andy Gospodarek 679e8a0f0a e1000e: stop unnecessary polling when using msi-x
The last hunk of this commit:

    commit 12d04a3c12
    Author: Alexander Duyck <alexander.h.duyck@intel.com>
    Date:   Wed Mar 25 22:05:03 2009 +0000

        e1000e: commonize tx cleanup routine to match e1000 & igb

changed the logic for determining if we should call napi_complete or
not at then end of a napi poll.

If the NIC is using MSI-X with no work to do in ->poll, net_rx_action
can just spin indefinitely on older kernels and for 2 jiffies on newer
kernels since napi_complete is never called and budget isn't
decremented.

Discovered and verified while testing driver backport to an older
kernel.

An mbox cmd is protected via a spin_lock(cmd_lock) and not spin_lock_bh() as it is undesirable

This can lockup a cmd in progress in process context.

This forces every update of tx ring producer to check for
availability of space for next full TSO command. Earlier
firmware control commands didn't care to pause tx queue.

Stop the tx queue if there's not enough space to transmit one full
LSO command left on the tx ring after current transmit. This avoids
returning NETDEV_TX_BUSY after checking distance between producer
and consumer on every cpu.

Restart the tx queue only if we have cleaned up enough tx
descriptors.

Jiri Pirko 31278e7147 net: group address list and its count
This patch is inspired by patch recently posted by Johannes Berg. Basically what
my patch does is to group list and a count of addresses into newly introduced
structure netdev_hw_addr_list. This brings us two benefits:
1) struct net_device becames a bit nicer.
2) in the future there will be a possibility to operate with lists independently
   on netdevices (with exporting right functions).
I wanted to introduce this patch before I'll post a multicast lists conversion.

Stephen Hemminger 6cc90a5a60 sky2: don't look for VPD size
The code to compute VPD size didn't handle some systems that use
chip without VPD. Also some of the newer chips use some additional
registers to store the actual size, and wasn't worth putting the
additional complexity in, so just remove the code.

No big loss since the code to set the VPD size was only a
convenience so that utilities would not read the extra space past
the end of the available VPD.

Move the first PCI config read earlier to detect bad hardware
where it returns all ones and refuse loading driver before furthur
damage.

GeunSik Lim 156f5a7801 debugfs: Fix terminology inconsistency of dir name to mount debugfs filesystem.
Many developers use "/debug/" or "/debugfs/" or "/sys/kernel/debug/"
directory name to mount debugfs filesystem for ftrace according to
./Documentation/tracers/ftrace.txt file.

And, three directory names(ex:/debug/, /debugfs/, /sys/kernel/debug/) is
existed in kernel source like ftrace, DRM, Wireless, Documentation,
Network[sky2]files to mount debugfs filesystem.

debugfs means debug filesystem for debugging easy to use by greg kroah
hartman. "/sys/kernel/debug/" name is suitable as directory name
of debugfs filesystem.
- debugfs related reference: http://lwn.net/Articles/334546/

Fix inconsistency of directory name to mount debugfs filesystem.

Greg Kroah-Hartman 1b713e0050 xen: remove driver_data direct access of struct device from more drivers
In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

Abhijeet Kolekar 8a9b99267c iwlwifi/iwl3945: fix suspend resume association bug
Patch fixes the following bugs at
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=2005
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=2007

If we suspend with an association and then resumed,
we need to synchronize the active rxon with staging rxon,
else we will get an error when iwl_alive_start try to commit
rxon and staging is set to channel 0. Before going to suspend
staging and active rxon are in sync. After resuming from the
suspend, iwl_mac_start is called and it clears the staging
rxon. Patch fixes the bug by not clearing the staging rxon
in iwl_mac_start.

Patch also adds similar fix to 3945.

Andrey Yurovsky b3781c7437 libertas: fix IEEE PS mode in GSPI driver
The card firmware does not set the Command Download Ready interrupt bit
when IEEE PS mode is enabled, preventing the driver from sending
commands (such as the command to exit IEEE PS mode) since there is no
indication that the card is ready to accept commands.

This patch works around the problem by using the the TX Download Ready
bit in place of the Command Download Ready Bit while in IEEE PS mode.
TX Download Ready is set in IEEE PS mode.

Cindy H Kao 0bcfc5ef01 wimax/i2400m: use -EL3RST to indicate device reset instead of -ERESTARTSYS
When the i2400m device resets, the driver code will force some
functions to return a -ERESTARTSYS error code, which can is used by
the caller to determine which recovery actions to take.

However, in certain situations the only thing that can be done is to
bubble up said error code to user space, for handling.

However, -ERESTARSYS was a poor choice, as it is supposed to be used
by the kernel only.

As such, replace -ERESTARTSYS with -EL3RST; as well, in
i2400m_msg_to_dev(), when the device is in boot mode (following a
recent reset), return -EL3RST instead of -ENODEV (meaning the device
is in bootrom mode after a reset, not that the device was
disconnected, and thus, normal commands cannot be executed).

When a device reset happens during firmware load [in
i2400m_dev_bootstrap()], __i2400m_dev_start() will retry a number of
times. However, for those retries to be able to accomplish anything,
the device's bootrom has to be reinitialized.

Thus, on the retry path, pass the I2400M_MAC_REINIT to the firmware
load code.

The current SDIO code was working in polling mode for boot-mode
(firmware load) mode. This was causing issues on some hardware.

Moved all the RX code to use a unified IRQ handler that based on the
type of data the device is sending can discriminate and decide which
is the right destination.

As well, all the reads from the device are made to be at least the
block size (256); the driver will ignore the rest when not needed.

Inaky Perez-Gonzalez 6e053d6c79 wimax/i2400m: don't reset device when bootrom init retries are exceeded
When i2400m_bootrom_init() fails to put the device into a state of
being ready to accept firmware, the driver was currently trying to
reset it if it failed to do so. This is not too useful; as part of
trying to put the device in the right state a few resets have already
been tried.

At this point, things are probably fried out and an extra reset might
do more harm than good (for example causing reseting of other
functions in the same composite device).

So it is left up to the callers to determine the error path to take
(at the end this is always i2400m_setup(), who depending on how many
retries are left, might give up on the device).

From a fix by Cindy H. Kao.

Dirk Brandewie 7308a0c239 wimax/i2400m: move boot time poke table out of common driver
This change moves the table of "pokes" performed on the device at boot
time to the bus specific portion of the driver.

Different models of the i2400m device supported by this driver require
different poke tables, thus having a single table that works for all
is impossible. For that, the table is moved to the bus-specific
driver, who can decide which table to use based on the specifics of
the device and point the generic driver to it.

Inaky Perez-Gonzalez ecddfd5ed7 wimax/i2400m: Allow bus-specific driver to specify retry count
The code that sets up the i2400m (firmware load and general driver
setup after it) includes a couple of retry loops.

The SDIO device sometimes can get in more complicated corners than the
USB one (due to its interaction with other SDIO functions), that
require trying a few more times.

To solve that, without having a failing USB device taking longer to be
considered dead, allow the retry counts to be specified by the
bus-specific driver, which the general driver takes as a parameter.

Inaky Perez-Gonzalez b4bd07e3b1 wimax/i2400m: don't reset device on i2400m_dev_shutdown()
i2400m_dev_shutdown() tried to reset the device to put it in a known
state before shutting down.

But that turned out to be pointless. We reach this case in two paths:

 1 - when the device resets, to clean up state
 2 - when the driver is unloaded, for the same

however, in both cases it is pointless; in (1) the device is already
reset, why do it again? in (2) we can't -- the USB stack, for example,
doesn't allow communicating with the device when the driver is being
unbound and if the device is disconnected, the device is gone already.

So just remove it. Leave the function as a placeholder for future
cleanups that will be done from data allocated by the driver during
device operation.

the FIFO (without payloads). The i2400m_tx_close() code already marked
said TX message (header) to be skipped and this function should be
doing nothing.

It is called anyway because it is part of a common "corner case" path
handling which takes care of more cases than only this one.

The tail room computation was also improved to take care of the case
when tx_in is at the end of the buffer boundary; tail_room has to be
modded (%) to the buffer size. To do that in a single well-documented
place, __i2400m_tx_tail_room() is introduced and used.

Treat i2400m->tx_in == 0 as a corner case and handle it accordingly.

Inaky Perez-Gonzalez c56affafdd wimax/i2400m: fix panic/warnings caused by missed check on empty TX message
In some situations, when a new TX message header is started, there
might be no space for data payloads. In this case the message is left
with zero payloads and the i2400m_tx_close() function has just to mark
it as "to skip". If it tries to go ahead it will overwrite things
because there is no space to add padding as defined by the
bus-specific layer. This can cause buffer overruns and in some stress
cases, panics.
