Don Fry 4cc5c47579 pcnet32: add missing check for pci_dma_mapping_error
The pci_map_single calls never checked for error. Add error checking
as requested by someone last year.  Tested on 79c972.

Don Fry 60e2e8b399 pcnet32: fix reallocation error
pcnet32_realloc_rx_ring() only worked on the first log2 number of
entries in the receive ring instead of the all the entries.
Replaced "1 << size" with more descriptive variable.
This is my original bug from 2006.  Found while testing another problem.
Tested on 79C972 and 79C976.

  conversion from PFNs to addresses where people assume that shifting an
  unsigned long left by PAGE_SHIFT results in a correct address.  This
  is not the case with C: the integer promotion happens at assignment

Ben Dooks f15c586d1d of_mdio: fix phy interrupt passing
The of_mdiobus_register_phy() is not setting phy->irq thus causing
some drivers to incorrectly assume that the PHY does not have an
IRQ associated with it. Not only do some drivers report no IRQ
they do not install an interrupt handler for the PHY.

Simplify the code setting irq and set the phy->irq at the same
time so that we cover the following issues, which should cover
all the cases the code will find:

- Set phy->irq if node has irq property and mdio->irq is NULL
- Set phy->irq if node has no irq and mdio->irq is not NULL
- Leave phy->irq as PHY_POLL default if none of the above

This fixes the issue:
 net eth0: attached PHY 1 (IRQ -1) to driver Micrel KSZ8041RNLI

to the correct:
 net eth0: attached PHY 1 (IRQ 416) to driver Micrel KSZ8041RNLI

the standard is not enforced.

Thomas Petazzoni 4b636b535d net: ethernet: update dependency and help text of mvneta
With the introduction of the support for Armada 375 and Armada 38x,
the hidden Kconfig option MACH_ARMADA_370_XP is being renamed to
MACH_MVEBU_V7. Therefore, the dependency that was used for the mvneta
driver can no longer work. This commit replaces this dependency by a
dependency on PLAT_ORION, which is used similarly for the mv643xx_eth
driver.

In addition to this, it takes this opportunity to adjust the
description and help text to indicate that the driver can is also used
for Armada 38x. Note that Armada 375 cannot use this driver as it has
a completely different networking unit, which will require a separate
driver.

Sergei Shtylyov e8f08ee0ad DT: net: document Ethernet bindings in one place
This patch is an attempt to gather the Ethernet related bindings in one file,
like it's done in the MMC and some other subsystems. It should save some of
the trouble of documenting several properties over and over in each binding
document, instead only making reference to the main file.

I have used the Embedded Power Architecture(TM) Platform Requirements (ePAPR)
standard as a base for the properties description, also documenting some ad-hoc
properties that have been introduced over time despite having direct analogs in
ePAPR.

====================
Please pull this batch of fixes intended for the 3.14 stream...

For the iwlwifi one, Emmanuel says:

"As explicitly written in the commit message, we prefer to disable Tx
AMPDU on NICs supported by iwldvm. This feature gives a big boost in
Tx performance, but the firmware is buggy and we can't rely on it.
Our hope is that most of the users out there want wifi to surf on
the web which means that they care more for Rx traffic than for Tx.
People who want to enable it can do so with the help of a module
parameter."

On top of that...

Dan Carpenter fixes a typo/thinko in ath5k.

Olivier Langlois fixes a couple of rtlwifi issues, one which leaves
IRQs disabled too long (causing a variety of problems elsewhere),
and one which fixes an incorrect return code when failing to enable
the NIC.

David S. Miller 82f148e992 Merge branch 'bonding'
Veaceslav Falico says:

====================
bonding: add an option to rely on unvalidated arp packets

v4 -> v5:
Again per Nik's advise correct the bond_opts restrictions for arp_validate
- set it the same as arp_interval.

v3 -> v4:
Per Nikolay's advise, remove the new bond_opts restriction on modes setting
for arp_validate.

v2 -> v3:
Per Jay's advise, use the 'filter' keyword instead of 'arp' one, and use
his text for documentation. Also, rebase on the latest net-next. Sorry for
the delay, didn't manage to send it before net-next was closed.

v1 -> v2:
Don't remove the 'all traffic' functionality - rather, add new arp_validate
options to specify that we want *only* unvalidated arps.

Currently, if arp_validate is off (0), slave_last_rx() returns the
slave->dev->last_rx, which is always updated on *any* packet received by
slave, and not only arps. This means that, if the validation of arps is
off, we're treating *any* incoming packet as a proof of slave being up, and
not only arps.

This might seem logical at the first glance, however it can cause a lot of
troubles and false-positives, one example would be:

The arp_ip_target is NOT accessible, however someone in the broadcast domain
spams with any broadcast traffic. This way bonding will be tricked that the
slave is still up (as in - can access arp_ip_target), while it's not.

The net_device->last_rx is already used in a lot of drivers (even though the
comment states to NOT do it :)), and it's also ugly to modify it from bonding.

However, some loadbalance setups might rely on the fact that even non-arp
traffic is a sign of slave being up - and we definitely can't break anyones
config - so an extension to arp_validate is needed.

So, to fix this, add an option for the user to specify if he wants to
filter out non-arp traffic on unvalidated slaves, remove the last_rx from
bonding, *always* call bond_arp_rcv() in slave's rx_handler (which is
bond_handle_frame), and if we spot an arp there with this option on - update
the slave->last_arp_rx - and use it instead of net_device->last_rx. Finally,
rename last_arp_rx to last_rx to reflect the changes.

Also rename slave->jiffies to ->last_link_up, to reflect better its
meaning, add the new option's documentation and update the arp_validate one
to be a bit more descriptive.

Veaceslav Falico 3fe68df97c bonding: always set recv_probe to bond_arp_rcv in arp monitor
Currently we only set bond_arp_rcv() if we're using arp_validate, however
this makes us skip updating last_arp_rx if we're not validating incoming
ARPs - thus, if arp_validate is off, last_arp_rx will never be updated.

Fix this by always setting up recv_probe = bond_arp_rcv, even if we're not
using arp_validate.

Currently we're updating the last_arp_rx only when we've validate the
packet, however afterwards we use it as 'ANY last packet received', but not
only validated ARPs.

Fix this by updating it in case of any packet received. It won't break the
arp_validation=0 because we, anyway, return the correct slave->dev->last_rx in
slave_last_rx().

Veaceslav Falico 13ac34a886 bonding: permit using arp_validate with non-ab modes
Currently it's disabled because it's sometimes hard, in typical configs, to
make it work - because of the nature how the loadbalance modes work - as
it's hard to deliver valid arp replies to correct slaves by the switch.

However we still can use arp_validation in loadbalance with several other
configs, per example with arp_validate == 2 for backup with one broadcast
domain, without the switch(es) doing any balancing - this way we'd be (a
bit more) sure that the slave is up.

So, enable it to let users decide which one works/suits them best. Also
correct the mode limitation from BOND_OPT_ARP_VALIDATE.

We're always called with rcu_read_lock() held (bond_arp_rcv() is only
called from bond_handle_frame(), which is rx_handler and always called
under rcu from __netif_receive_skb_core() ).

The slave active/passive and/or bonding params can change in-flight, however
we don't really care about that - we only modify the last time packet was
received, which is harmless.
