Wey-Yi Guy 399dcb8a36 iwlwifi: remove get_stats callback function
The low level transmission function is performed at uCode layer
for all the "agn" NICs, there is no statistics information available
for mac80211 get_stats() call. Remove the callback function to
avoid misleading information that returned success when indeed it is not
supported. Now return "not supported".

Johannes Berg 96ff564195 iwlwifi: work around passive scan issue
Some firmware versions don't behave properly when
passive scanning is requested on radar channels
without enabling active scanning on receiving a
good frame. Work around that issue by asking the
firmware to only enable the active scanning after
receiving a huge number of good frames, a number
that can never be reached during our dwell time.

mdiobus_register() calls device_register() which initializes the kobj of
the device. mdiobus_unregister() calls only device_del() so we have one
reference left. That one is leaving with mdiobus_free() which is only
called on remove.
Since I don't see any reason why mdiobus_register()/mdiobus_unregister()
should happen in ->open()/->close() I move them to probe & exit.

Dan Carpenter f7f7cc47fc iwl: cleanup: remove unneeded error handling
This is just a cleanup and doesn't change how the code works.

debugfs_create_dir() and debugfs_create_file() return an error pointer
(-ENODEV) if CONFIG_DEBUG_FS is not enabled, otherwise if an error occurs
they return NULL.  This is how they are implemented and what it says in
the DebugFS documentation.  DebugFS can not be compiled as a module.

As a result, we only need to check for error pointers and particularly
-ENODEV one time to know that DebugFS is enabled.  This patch keeps the
first check for error pointers and removes the rest.

The other reason for this patch, is that it silences some Smatch warnings.
Smatch sees the condition "(result != -ENODEV)" and assumes that it's
possible for "result" to equal -ENODEV.  If it were possible it would lead
to an error pointer dereference.  But since it's not, we can just remove
the check.

Helmut Schaa baff8006b5 rt2x00: rt2800lib: update rfcsr & bbp init code for SoC devices
Update the rfcsr and bbp init code for SoC devices to match with the
latest Ralink driver.

To have better control over which values are used for the register
initialization create a new function rt2800_is_305x_soc which checks
for SoC interface type, the correct RT chipset and the correct RF
chipset. This is based on the assumption that all rt305x SoC devices
use a rt2872 and rf3020/rf3021/rf3022.

In case an unknown RF chipset is found on a SoC device with a rt2872
don't treat it as rt305x and just print a message.

Juuso Oikarinen 82429d32ca wl1271: Rewrite hardware keep-alive handling
The driver had a join command without keep-alive restart procedures in the
channel changing code. After associated scans, the mac80211 does re-set the
current channel, causing the join to occur. This would stop the hardware
keep alive.

To make the joins safer in this respect, this patch adds a join function that
does the hardware-keep-alive magic along the join. This is now invoked in the
above mentioned scenario, and also other scenarios.

Juuso Oikarinen 16092b5ccc wl1271: Improve command polling
In testing I noticed that the wl1271 commands fall into two categories. In the
first category are "fast" commands, these mostly take only 0 or 1 polls to
complete, but occasionally upto 50 (giving a 0.5ms execution time.) In the
second category, the command completion takes well more than 0.5ms (from
1.5ms upwards.)

This patch fixes command polling such that it is optimal for the fast commands,
but also allows sleep for the longer ones.

Steve Hodgson 41b7e4c326 sfc: Extend the legacy interrupt workarounds
Siena has two problems with legacy interrupts:
  1. There is no synchronisation between the ISR read completion,
     and the interrupt deassert message.
  2. A downstream read at the "wrong" moment can return 0, and
     suppress generating the next interrupt.

Falcon should suffer from both of these, and it appears it does.
Enable EFX_WORKAROUND_15783 on Falcon as well.

Also, when we see queues == 0, ensure we always schedule or rearm
every event queue.

Elina Pasheva eb4fd8cd35 net/usb: add sierra_net.c driver
Re-submitted based on comments from netdev community.
Summary of the changes:
1. Improved error handling.
2. Added the missing timeout arguments to usb_control_msg().

The following is a new Linux driver which exposes certain models of Sierra
Wireless modems to the operating system as Network Interface Cards (NICs).

This driver requires a version of the sierra.c driver which supports
blacklisting to work properly. The blacklist in sierra.c rejects the interfaces
claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts
(i.e. whitelists) the interface(s) used for USB-to-WWAN traffic.
The version of sierra.c which supports blacklisting is
available from the sierra wireless knowledge base page for older kernels. It is
also available in Linux kernel starting from version 2.6.31.

This driver works with all Sierra Wireless devices configured with PID=68A3
like USB305, USB306 provided the corresponding firmware version is I2.0
(for USB305) or M3.0 (for USB306) and later.
This driver will not work with earlier firmware versions than the ones shown
above. In this case the driver will issue an error message indicating
incompatibility and will not serve the device's USB-to-WWAN interface.

Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c.
A series of hook functions are provided in sierra_net.c which are called by
usbnet.c in response to a particular condition such as receipt or transmission
of a data packet. As such, usbnet.c does most of the work of making
a modem appear to the system as a network device and for properly exchanging
traffic between the USB subsystem and the Network card interface.
Sierra_net.c is concerned with managing the data exchanged between the
USB-to-WWAN interface and the upper layers of the operating system.

Michael Chan 212f9934af bnx2: Prevent "scheduling while atomic" warning with cnic, bonding and vlan.
The bonding driver calls ndo_vlan_rx_register() while holding bond->lock.
The bnx2 driver calls bnx2_netif_stop() to stop the rx handling while
changing the vlgrp.  The call also stops the cnic driver which sleeps
while the bond->lock is held and cause the warning.

This code path only needs to stop the NAPI rx handling while we are
changing the vlgrp.  Since no reset is going to occur, there is no need
to stop cnic in this case.  By adding a parameter to bnx2_netif_stop()
to skip stopping cnic, we can avoid the warning.

Michael Chan c441b8d2cb bnx2: Fix lost MSI-X problem on 5709 NICs.
It has been reported that under certain heavy traffic conditions in MSI-X
mode, the driver can lose an MSI-X vector causing all packets in the
associated rx/tx ring pair to be dropped.  The problem is caused by
the chip dropping the write to unmask the MSI-X vector by the kernel
(when migrating the IRQ for example).

This can be prevented by increasing the GRC timeout value for these
register read and write operations.

Thanks to Dell for helping us debug this problem.

John Fastabend c0dfb90e5b ixgbe: ixgbe_down needs to stop dev_watchdog
There is a small race between when the tx queues are stopped
and when netif_carrier_off() is called in ixgbe_down.  If the
dev_watchdog() timer fires during this time it is possible for
a false tx timeout to occur.

This patch moves the netif_carrier_off() so that it is called before
the tx queues are stopped preventing the dev_watchdog timer from
detecting false tx timeouts.  The race is seen occosionally when
FCoE or DCB settings are being configured or changed.

Testing note, running ifconfig up/down will not reproduce this
issue because dev_open/dev_close call dev_deactivate() and then
dev_activate().

absolutely lowest latency setting in the hardware.  This disables
writeback batching and anything else that relies upon a delayed

user sets rx-usecs to zero, the driver will respect that setting
over using RSC, and automatically disable RSC.  If rx-usecs is
used to set the EITR value to 0, then the driver should disable
LRO (aka RSC) internally until EITR is set to non-zero again.

Bruce Allan 6f461f6c7c e1000e: enable/disable ASPM L0s and L1 and ERT according to hardware errata
Prompted by a previous patch submitted by Matthew Garret <mjg@redhat.com>,
further digging into errata documentation reveals the current enabling or
disabling of ASPM L0s and L1 states for certain parts supported by this
driver are incorrect.  82571 and 82572 should always disable L1.  For
standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled,
and for jumbo frames 82573/82574 must disable L1.  This allows for some
parts to enable L1 in certain configurations leading to better power
savings.

Also according to the same errata, Early Receive (ERT) should be disabled
on 82573 when using jumbo frames.

Quote from comment #17:
"The problem is the innocent looking moving of the tx processing to
 after the rx processing in the tasklet. Quoting from the changelog:
  This patch does it the same way, except that it also prioritize
  rx data processing, simply because tx routines *can* wait.

 This is causing an issue with us referencing already freed memory,
 because some skb's we transmit, we immediately receive back, such
 as those for reading the eeprom (*) and getting stats.

 What can happen because of the moving of the tx processing to after
 the rx processing is that when the tasklet first runs after doing a
 special skb tx (such as eeprom) we've already received the answer
 to it.

 Then the rx processing ends up calling p54_find_and_unlink_skb to
 find the matching tx skb for the just received special rx skb and
 frees the tx skb.

 Then after the processing of the rx skb answer, and thus freeing
 the tx skb, we go process the completed tx ring entires, and then
 dereference the free-ed skb, to see if it should free free-ed by
 p54p_check_tx_ring()."

John W. Linville d53cdbb94a ssb: do not read SPROM if it does not exist
Attempting to read registers that don't exist on the SSB bus can cause
hangs on some boxes.  At least some b43 devices are 'in the wild' that
don't have SPROMs at all.  When the SSB bus support loads, it attempts
to read these (non-existant) SPROMs and causes hard hangs on the box --
no console output, etc.

This patch adds some intelligence to determine whether or not the SPROM
is present before attempting to read it.  This avoids those hard hangs
on those devices with no SPROM attached to their SSB bus.  The
SSB-attached devices (e.g. b43, et al.) won't work, but at least the box
will survive to test further patches. :-)

Alan Cox 401da6aea3 e100: Fix the TX workqueue race
Nothing stops the workqueue being left to run in parallel with close or a
few other operations. This causes double unmaps and the like.

See kerneloops.org #1041230 for an example

Stephen Hemminger bf73130d7f sky2: add support for receive hashing
Sky2 hardware supports hardware receive hash calculation.
Now that Receive Packet Steering is available, add support
to enable it.

This version does not depend on CONFIG_RPS. Also set_flags rejects
all values except RXHASH, so driver won't have to change next time
somebody adds a new one.

Anton Vorontsov 7ce97d4f78 gianfar: Fix potential oops during OF address translation
gianfar driver may pass NULL pointer to the of_translate_address(),
which may lead to a kernel oops. Fix this by using of_iomap(), which
is also much simpler and shorter.

Anton Vorontsov 3b1fd3e55a fsl_pq_mdio: Fix kernel oops during OF address translation
Old P1020RDB device trees were not specifing tbipa address for
MDIO nodes, which is now causing this kernel oops:

 ...
 eth2: TX BD ring size for Q[6]: 256
 eth2: TX BD ring size for Q[7]: 256
 Unable to handle kernel paging request for data at address 0x00000000
 Faulting instruction address: 0xc0015504
 Oops: Kernel access of bad area, sig: 11 [#1]
 ...
 NIP [c0015504] memcpy+0x3c/0x9c
 LR [c000a9f8] __of_translate_address+0xfc/0x21c
 Call Trace:
 [df839e00] [c000a94c] __of_translate_address+0x50/0x21c (unreliable)
 [df839e50] [c01a33e8] get_gfar_tbipa+0xb0/0xe0
 ...

The old device trees are buggy, though having a dead ethernet is
better than a dead kernel, so fix the issue by using of_iomap().

Also, a somewhat similar issue exist in the probe() routine, though
there the oops is only a possibility. Nonetheless, fix it too.

stephen hemminger efe91932e7 sky2: size status ring based on Tx/Rx ring
Sky2 status ring must be big enough to handle worst case number
of status messages. It was being oversized (to handle dual port cards),
and excessive number of tx ring entries were allowed. This patch reduces
the footprint and makes sure the value is enough.

Later patch to add RSS increases the number of possible Rx status elements.
