222ca8e0c1 net: macb: Disable half duplex gigabit on Zynq
According to the Zynq TRM, gigabit half duplex is not supported.  Add a
new cap and compatible string so Zynq can avoid advertising that mode.

44f6731d8b cdc_ncm: Fix tx_bytes statistics
The tx_curr_frame_payload field is u32. When we try to calculate a
small negative delta based on it, we end up with a positive integer
close to 2^32 instead.  So the tx_bytes pointer increases by about
2^32 for every transmitted frame.

Fix by calculating the delta as a signed long.

c15e10e71c net: phy: Make sure phy_start() always re-enables the phy interrupts
This is an alternative way of fixing:
 commit db9683fb41 ("net: phy: Make sure PHY_RESUMING state change
                      is always processed")

When the PHY state transitions from PHY_HALTED to PHY_RESUMING, there are
two things we need to do:
1). Re-enable interrupts (and power up the physical link, if powered down)
2). Update the PHY state and net-device based on the link status.

There's no strict reason why #1 has to be done from within the main
phy_state_machine() function. There is a risk that other changes to the
PHY (e.g. setting speed/duplex, which calls phy_start_aneg()) could cause
a subsequent state transition before phy_state_machine() has processed
the PHY_RESUMING state change. This would leave the PHY with interrupts
disabled and/or still in the BMCR_PDOWN/low-power mode.

Moving enabling the interrupts and phy_resume() into phy_start() will
guarantee this work always gets done. As the PHY is already in the HALTED
state and interrupts are disabled, it shouldn't conflict with any work
being done in phy_state_machine(). The downside of this change is that if
the PHY_RESUMING state is ever entered from anywhere else, it'll also have
to repeat this work.

13c3ed6a92 vxlan: correct typo in call to unregister_netdevice_queue
By inspection, this appears to be a typo.  The gating comparison
involves vxlan->dev rather than dev.  In fact, dev is the iterator in
the preceding loop above but it is actually constant in the 2nd loop.

Use of dev seems to be a bad cut-n-paste from the prior call to
unregister_netdevice_queue.  Change dev to vxlan->dev, since that is
what is actually being checked.

ed2a80ab7b rtnl/bond: don't send rtnl msg for unregistered iface
Before the patch, the command 'ip link add bond2 type bond mode 802.3ad'
causes the kernel to send a rtnl message for the bond2 interface, with an
ifindex 0.

'ip monitor' shows:
0: bond2: <BROADCAST,MULTICAST,MASTER> mtu 1500 state DOWN group default
    link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff

    link/ether ea:3e:1f:53:92:7b brd ff:ff:ff:ff:ff:ff
[snip]

The patch fixes the spotted bug by checking in bond driver if the interface
is registered before calling the notifier chain.
It also adds a check in rtmsg_ifinfo() to prevent this kind of bug in the
future.

db9683fb41 net: phy: Make sure PHY_RESUMING state change is always processed
If phy_start_aneg() was called while the phydev is in the PHY_RESUMING
state, then its state would immediately transition to PHY_AN (or
PHY_FORCING). This meant the phy_state_machine() never processed the
PHY_RESUMING state change, which meant interrupts weren't enabled for the
PHY. If the PHY used low-power mode (i.e. using BMCR_PDOWN), then the
physical link wouldn't get powered up again.

There seems no point for phy_start_aneg() to make the PHY_RESUMING -->
PHY_AN transition, as the state machine will do this anyway. I'm not sure
about the case where autoneg is disabled, as my patch will change
behaviour so that the PHY goes to PHY_NOLINK instead of PHY_FORCING. An
alternative solution would be to move the phy_config_interrupt() and
phy_resume() work out of the state machine and into phy_start().

The background behind this: we're running linux v3.16.7 and from user-space
we want to enable the eth port (i.e. do a SIOCSIFFLAGS ioctl with the
IFF_UP flag) and immediately afterward set the interface's speed/duplex.
Enabling the interface calls .ndo_open() then phy_start() and the PHY
transitions PHY_HALTED --> PHY_RESUMING. Setting the speed/duplex ends up
calling phy_ethtool_sset(), which calls phy_start_aneg() (meanwhile the
phy_state_machine() hasn't processed the PHY_RESUMING state change yet).

7e14069651 net: phy: Allow EEE for all RGMII variants
RGMII interfaces come in multiple flavors: RGMII with transmit or
receive internal delay, no delays at all, or delays in both direction.

This change extends the initial check for PHY_INTERFACE_MODE_RGMII to
cover all of these variants since EEE should be allowed for any of these
modes, since it is a property of the RGMII, hence Gigabit PHY capability
more than the RGMII electrical interface and its delays.

c1c52db16e net/mlx4: Avoid 'may be used uninitialized' warnings
With a cross-compiler based on gcc-4.9, I see warnings like the following:

  drivers/net/ethernet/mellanox/mlx4/resource_tracker.c: In function 'mlx4_SW2HW_CQ_wrapper':
  drivers/net/ethernet/mellanox/mlx4/resource_tracker.c:3048:10: error: 'cq' may be used uninitialized in this function [-Werror=maybe-uninitialized]
    cq->mtt = mtt;

I think the warning is spurious because we only use cq when
cq_res_start_move_to() returns zero, and it always initializes *cq in that
case.  The srq case is similar.  But maybe gcc isn't smart enough to figure
that out.

Initialize cq and srq explicitly to avoid the warnings.

Doing clock-mode-select in this cause causes kszphy_probe to

cd9c399777 bnx2x: limit fw delay in kdump to 5s after boot
Commit 12a8541d5c "bnx2x: Delay during kdump load" added a 5 seconds
delay to bnx2x's probe function in the kdump case to let the firmware
realize the old driver is gone.

The problem with the delay is that it is per-device, so if you have
several bnx2x NICs in NPAR mode, the delays can accumulate to minutes.

Fix it by adjusting the delay so that we do not wait more than
necessary, i.e. no more delaying after 5 seconds of kernel boot time.

3e4336a65a usbnet: avoid integer overflow in start_xmit
transfer_buffer_length is of type u32. It's therefore wrong to assign it
to a signed integer. This patch avoids the overflow.

It's worth noting that entry->length here is a long; perhaps it would be
beneficial at somepoint to change this to be unsigned as well, if
nothing else relies on its signedness for error conditions or the like.

240b23c426 netxen_nic: use spin_[un]lock_bh around tx_clean_lock (2)
This patch should have been part of the previous patch having the
same summary. See  http://marc.info/?l=linux-kernel&m=143039470103795&w=2
Unfortunately, I didn't check to see where else this lock was used before
submitting that patch. This should take care of it for netxen_nic, as I
did a thorough search this time.

To recap from the original patch; although testing this driver with
DEBUG_LOCKDEP and DEBUG_SPINLOCK enabled did not produce any traces,
it would be more prudent in the case of tx_clean_lock to use _bh
versions of spin_[un]lock, since this lock is manipulated in both
the process and softirq contexts.

This patch was tested for functionality and regressions with netperf
and DEBUG_LOCKDEP and DEBUG_SPINLOCK enabled.

965b2aa78f net/smsc911x: fix irq resource allocation failure
When smsc911x uses GPIO as the interrupt controller, and if both are
loaded as modules, we get following error:

"smsc911x: Could not allocate irq resource"

This issue is because of smsc911x using platform_get_resource to get
device tree based irq resource.

commit "9ec36ca (of/irq: do irq resolution in platform_get_irq)" and
commit "7085a7 (drivers: platform: parse IRQ flags from resources)" add
support in platform_get_irq to resolve irq and irq_flags respectively
for both modern device tree and legacy static platform data platforms.

Modify smsc911x driver to use platform_get_irq to pick up irq resource
correctly and use irq_get_trigger_type to get the IRQ trigger flags.

efdbd2b30c macvlan: Propagate promiscuity setting to lower devices.
When a macvlan device is placed in promiscuous mode, it currently
just sets it's multicast mask to permissive, but doesn't change
the state of the lower device.  As a result, not all multicast
traffic can be received on such device.  Additionally, none of
a vlan traffic can be received on such device as well.
This patch propagates the promiscuous mode setting to lower device
so that lower device may receive all packets that macvlan may
be interested in.

e7fcd5439f ixgbevf: Use dev_kfree_skb_any in xmit path, not dev_kfree_skb
With netpoll making use of the transmit function it is possible for the
ndo_start_xmit function to be called with irqs disabled.  As such we need
to use dev_kfree_skb_any in the Tx cleanup path for frames that are
dropped.

eb78139790 r8169: Do not use dev_kfree_skb in xmit path
The function r8169_csum_workaround is called in the ndo_start_xmit path of
the r8169 driver.  As such it should not be using dev_kfree_skb as it is
not irq safe, so instead we should be using dev_kfree_skb_any for freeing
in the dropped path, and dev_consume_skb_any for any frames that were
transmitted.

5793affe8c net: can: xilinx_can: fix extended frame handling
Using IDR_SRR in RXFIFO_ID to test for the presence of data is only
valid for standard frames. For extended frames the bit is always 1 and
IDR_RTR should be used instead. This patch switches the check to use
CAN_RTR_FLAG which is correctly set when reading the ID.

The patch also changes the DW1/DW2 to be read unconditionally, since
this is necessary to remove the frame from the RXFIFO.

RGMII-ID uses an internal delay within the transmitter or receiver. This
feature is phy specific. The rest of the communication is normal RGMII.

So the fec driver has to check for all RGMII modes, not only
'PHY_INTERFACE_MODE_RGMII'.

07841f9d94 net/mlx4_en: Schedule napi when RX buffers allocation fails
When system is out of memory, refilling of RX buffers fails while
the driver continue to pass the received packets to the kernel stack.
At some point, when all RX buffers deplete, driver may fall into a
sleep, and not recover when memory for new RX buffers is once again
availible. This is because hardware does not have valid descriptors,
so no interrupt will be generated for the driver to return to work
in napi context. Fix it by schedule the napi poll function from
stats_task delayed workqueue, as long as the allocations fail.

c232d8a8bb netxen_nic: use spin_[un]lock_bh around tx_clean_lock
While testing this driver with DEBUG_LOCKDEP and DEBUG_SPINLOCK
enabled did not produce any traces, it would be more prudent in the
case of tx_clean_lock to use spin_[un]lock_bh, since this lock is
manipulated in both the process and softirq contexts.

This patch was tested for functionality and regressions with netperf
and DEBUG_LOCKDEP and DEBUG_SPINLOCK enabled.
