In case an interface has been brought down before entering S3, and then
brought up out of S3, all the initialization done during
bcmgenet_probe() by bcmgenet_mii_init() calling bcmgenet_mii_config() is
just lost since register contents are restored to their reset values.
Re-apply this configuration anytime we call bcmgenet_open() to make sure
our port multiplexer is properly configured to match the PHY interface.
Since we are now calling bcmgenet_mii_config() everytime bcmgenet_open()
is called, make sure we only print the message during initialization
time not to pollute the console.

phy_disconnect() is the only way to guarantee that we are not going to
schedule more work on the PHY state machine workqueue for that
particular PHY device.
This fixes an issue where a network interface was suspended prior to a
system suspend/resume cycle and would then be resumed as part of
mdio_bus_resume(), since the GENET interface clocks would have been
disabled, this basically resulted in bus errors to appear since we are
invoking the GENET driver adjust_link() callback.

When advertised capabilities are changed with mii-tool, such as:
mii-tool -A 10baseT
the existing handler has two errors.
- An actual PHY register value is provided by mii-tool, and this
must be mapped to internal state with mii_adv_to_ethtool_adv_t().
- The PHY state machine needs to be told that autonegotiation has
again been performed. If not, the MAC will not be notified of
the new link speed and duplex, resulting in a possible config
mismatch.

In ppp_ioctl(), bpf_prog_create() is called inside ppp_lock, which
eventually calls vmalloc() and hits BUG_ON() in vmalloc.c. This patch
works around the problem by moving the allocation outside the lock.
The bug was revealed by the recent change in net/core/filter.c, as it
allocates via vmalloc() instead of kmalloc() now.

tunnel is set
Currenly we only support Large-Send and TX checksum offloads for
encapsulated traffic of type VXLAN. We must make sure to advertize
these offloads up to the stack only when VXLAN tunnel is set.
Failing to do so, would mislead the the networking stack to assume
that the driver can offload the internal TX checksum for GRE packets
and other buggy schemes.

When doing GRO processing for UDP tunnels, we never add
SKB_GSO_UDP_TUNNEL to gso_type - only the type of the inner protocol
is added (such as SKB_GSO_TCPV4). The result is that if the packet is
later resegmented we will do GSO but not treat it as a tunnel. This
results in UDP fragmentation of the outer header instead of (i.e.) TCP
segmentation of the inner header as was originally on the wire.

Congestion Threshold
Free List Starvation Threshold needs to be larger than the SGE's Egress
Congestion Threshold or we'll end up in a mutual stall where the driver waits
for Ingress Packets to drive replacing Free List Pointers and the SGE waits for
Free List Pointers before pushing Ingress Packets to the host.

commit 3cc81d85ee01 ("asix: Don't reset PHY on if_up for ASIX 88772")
causes the ethernet on Arndale to no longer function. This appears to
be because the Arndale ethernet requires a full reset before it will
function correctly, however simply reverting the above patch causes
problems with ethtool settings getting reset.
It seems the problem is that the ethernet is not properly reset during
bind, and indeed the code in ax88772_bind that resets the device is a
very small subset of the actual ax88772_reset function. This patch uses
ax88772_reset in place of the existing reset code in ax88772_bind which
removes some code duplication and fixes the ethernet on Arndale.
It is still possible that the original patch causes some issues with
suspend and resume but that seems like a separate issue and I haven't
had a chance to test that yet.

commit 1b7bde6d659d ("net: fec: implement rx_copybreak to improve rx performance")
introduced a regression for i.MX28. The swap_buffer() function doing
the endian conversion of the received data on i.MX28 may access memory
beyond the actual packet size in the DMA buffer. fec_enet_copybreak()
does not copy those bytes, so that the last bytes of a packet may be
filled with invalid data after swapping.
This will likely lead to checksum errors on received packets.
E.g. when trying to mount an NFS rootfs:
UDP: bad checksum. From 192.168.1.225:111 to 192.168.100.73:44662 ulen 36
Do the byte swapping and copying to the new skb in one go if
necessary.

====================
pull request: wireless 2014-11-06
Please pull this batch of fixes intended for the 3.18 stream...
For the mac80211 bits, Johannes says:
"This contains another small set of fixes for 3.18, these are all
over the place and most of the bugs are old, one even dates back
to the original mac80211 we merged into the kernel."
For the iwlwifi bits, Emmanuel says:
"I fix here two issues that are related to the firmware
loading flow. A user reported that he couldn't load the
driver because the rfkill line was pulled up while we
were running the calibrations. This was happening while
booting the system: systemd was restoring the "disable
wifi settings" and that raised an RFKILL interrupt during
the calibration. Our driver didn't handle that properly
and this is now fixed."
Please let me know if there are problems!

When we reuse the rx buffer, we need to update the desc. If not hardware sees
stale value.
In the following crash, when mtu is changed, hardware sees old rx buffer value
and crashes on skb_put.
Fix this by using enic_queue_rq_desc helper function which updates the necessary
desc.

ATM, txq_reclaim will dequeue and free an skb for each tx desc released
by the hw that has TX_LAST_DESC set. However, in case of TSO, each
hw desc embedding the last part of a segment has TX_LAST_DESC set,
losing the one-to-one 'last skb frag'/'TX_LAST_DESC set' correspondance,
which causes data corruption.
Fix this by checking TX_ENABLE_INTERRUPT instead of TX_LAST_DESC, and
warn when trying to dequeue from an empty txq (which can be symptomatic
of releasing skbs prematurely).

This patch is to fix the atomicity when suspend and resume the
driver. The clk api have been changed (as reported by Hao Liang)
and the skb allocation is done out of the hw setup function and

This patch aims to fix the concurrency in eee initialization
inside the stmmac driver and related warnings when enable
DEBUG_ATOMIC_SLEEP.
Prior this patch, the stmmac_eee_init could be called in several places
as shown below:
stmmac_open stmmac_resume PHY Layer
| | |
stmmac_hw_setup stmmac_adjust_link
| | stmmac ethtool
|__________________________|______________|
|
stmmac_eee_init
The patch removes the stmmac_eee_init call inside the stmmac_hw_setup
that is unnecessary. It is sufficient to call it in the adjust_link to
always guarantee that EEE is always configured at mac level too.
Fixing the lock protection now it is covered another case (not
considered before). The stmmac_eee_init could be called by the ethtool
so critical sections must be protected inside this function too.

Microblaze is a fpga soft core, it can be customized easily, which may
cause many various hardware version strings.
So the original fix patch based on hard-coded compatible version strings
is not a good idea (although it is correct for current issue). For it,
there will be a new solving way soon (which based on the device tree).
The original issue is related with qemu, so can only change the hardware
version string in qemu for it, then keep the original driver no touch (
qemu is for virtualization which has much easier life than real world).

When VLAN is in use in macvtap_put_user, we end up setting
csum_start to the wrong place. The result is that the whoever
ends up doing the checksum setting will corrupt the packet instead
of writing the checksum to the expected location, usually this
means writing the checksum with an offset of -4.
This patch fixes this by adjusting csum_start when VLAN tags are
detected.

We set the flag TUN_PKT_STRIP if the user buffer provided is too
small to contain the entire packet plus meta-data. However, this
has been broken ever since we added GSO meta-data. VLAN acceleration
also has the same problem.
This patch fixes this by taking both into account when setting the
TUN_PKT_STRIP flag.
The fact that this has been broken for six years without anyone
realising means that nobody actually uses this flag.

If the RFkill interrupt fires while we calibrate, it would
make the firmware fail and the driver wasn't able to recover.
Change the flow so that the driver will kill the firmware
in that case.
Since we have now two flows that are calling
trans_stop_device (the RFkill interrupt and the
op_mode_mvm_start function) - we need to better sync this.
Use the STATUS_DEVICE_ENABLED in the pcie transport in an
atomic way to achieve this.
This fixes: https://bugzilla.kernel.org/show_bug.cgi?id=86231

The SMC91x is written to explicitly look up the IRQ resource
from the platform device and extract the IRQ and flags, however
the platform_get_irq() does additional things, like call
of_irq_get() in the device tree case, which will translate
the IRQ using the irqdomain and defer the probe if the
IRQ host cannot be found.
As we're not looking up the resource, this will not retrieve
the IRQ flags, but that is better done using
irqd_get_trigger_type(), as the trigger is what the driver
wants to modify. We take care to preserve the semantics that
will make the trigger type provided from the resource
override any local specifier.
Tested on the Nomadik NHK15 which has its SMC91x IRQ line
connected to a STMPE2401 GPIO expander on I2C.

Callers of bcm_sysport_init_tx_ring() can currently fail, and will
always call bcm_sysport_fini_tx_ring() in a loop ending at the number of
TX queues (32) without checking if the TX ring was successfully

Update bcm_sysport_fini_tx_ring() to return early and avoid a crash
de-referencing ring->cbs if the TX ring was not initialized, since
ring->cbs is the last part of the initialization done by
bcm_sysport_init_tx_ring() that could fail.

Pull ACPI and power management fixes from Rafael Wysocki:
"These are fixes received after my previous pull request plus one that
has been in the works for quite a while, but its previous version
caused problems to happen, so it's been deferred till now.
Fixed are two recent regressions (MFD enumeration and cpufreq-dt),
ACPI EC regression introduced in 3.17, system suspend error code path
regression introduced in 3.15, an older bug related to recovery from
failing resume from hibernation and a cpufreq-dt driver issue related
to operation performance points.
Specifics:
- Fix a crash on r8a7791/koelsch during resume from system suspend
caused by a recent cpufreq-dt commit (Geert Uytterhoeven).
- Fix an MFD enumeration problem introduced by a recent commit adding
ACPI support to the MFD subsystem that exposed a weakness in the
ACPI core causing ACPI enumeration to be applied to all devices
associated with one ACPI companion object, although it should be
used for one of them only (Mika Westerberg).
- Fix an ACPI EC regression introduced during the 3.17 cycle causing
some Samsung laptops to misbehave as a result of a workaround
targeted at some Acer machines. That includes a revert of a commit
that went too far and a quirk for the Acer machines in question.
From Lv Zheng.
- Fix a regression in the system suspend error code path introduced
during the 3.15 cycle that causes it to fail to take errors from
asychronous execution of "late" suspend callbacks into account
(Imre Deak).
- Fix a long-standing bug in the hibernation resume error code path
that fails to roll back everything correcty on "freeze" callback
errors and leaves some devices in a "suspended" state causing more
breakage to happen subsequently (Imre Deak).
- Make the cpufreq-dt driver disable operation performance points
that are not supported by the VR connected to the CPU voltage plane
with acceptable tolerance instead of constantly failing voltage
scaling later on (Lucas Stach)"

Pull PCI fixes from Bjorn Helgaas:
"These changes, intended for v3.18, fix:
Sysfs
- Fix "enable" filename change (Greg Kroah-Hartman)
An unintentional sysfs filename change in commit 5136b2da770d
("PCI: convert bus code to use dev_groups"), which appeared in
v3.13, changed "enable" to "enabled", and this changes it back.
Old users of "enable" are currently broken and will be helped by
this change. Anything that started to use "enabled" after v3.13
will be broken by this change. If necessary, we can add a symlink
to make both work, but this patch doesn't do that.
PCI device hotplug
- Revert duplicate merge (Kamal Mostafa)
A mistaken duplicate merge that added a check twice. Nothing's
broken; this just removes the unnecessary code.
Freescale i.MX6
- Wait for clocks to stabilize after ref_en (Richard Zhu)
An i.MX6 clock problem that prevents mx6 nitrogen boards from booting"

Pull networking fixes from David Miller:
"A bit has accumulated, but it's been a week or so since my last batch
of post-merge-window fixes, so...
1) Missing module license in netfilter reject module, from Pablo.
Lots of people ran into this.
2) Off by one in mac80211 baserate calculation, from Karl Beldan.
3) Fix incorrect return value from ax88179_178a driver's set_mac_addr
op, which broke use of it with bonding. From Ian Morgan.
4) Checking of skb_gso_segment()'s return value was not all
encompassing, it can return an SKB pointer, a pointer error, or
NULL. Fix from Florian Westphal.
This is crummy, and longer term will be fixed to just return error
pointers or a real SKB.
6) Encapsulation offloads not being handled by
skb_gso_transport_seglen(). From Florian Westphal.
7) Fix deadlock in TIPC stack, from Ying Xue.
8) Fix performance regression from using rhashtable for netlink
sockets. The problem was the synchronize_net() invoked for every
socket destroy. From Thomas Graf.
9) Fix bug in eBPF verifier, and remove the strong dependency of BPF
on NET. From Alexei Starovoitov.
10) In qdisc_create(), use the correct interface to allocate
->cpu_bstats, otherwise the u64_stats_sync member isn't
initialized properly. From Sabrina Dubroca.
11) Off by one in ip_set_nfnl_get_byindex(), from Dan Carpenter.
12) nf_tables_newchain() was erroneously expecting error pointers from
netdev_alloc_pcpu_stats(). It only returna a valid pointer or
NULL. From Sabrina Dubroca.
13) Fix use-after-free in _decode_session6(), from Li RongQing.
14) When we set the TX flow hash on a socket, we mistakenly do so
before we've nailed down the final source port. Move the setting
deeper to fix this. From Sathya Perla.
15) NAPI budget accounting in amd-xgbe driver was counting descriptors
instead of full packets, fix from Thomas Lendacky.
16) Fix total_data_buflen calculation in hyperv driver, from Haiyang
Zhang.
17) Fix bcma driver build with OF_ADDRESS disabled, from Hauke
Mehrtens.
18) Fix mis-use of per-cpu memory in TCP md5 code. The problem is
that something that ends up being vmalloc memory can't be passed
to the crypto hash routines via scatter-gather lists. From Eric
Dumazet.
19) Fix regression in promiscuous mode enabling in cdc-ether, from
Olivier Blin.
20) Bucket eviction and frag entry killing can race with eachother,
causing an unlink of the object from the wrong list. Fix from
Nikolay Aleksandrov.
21) Missing initialization of spinlock in cxgb4 driver, from Anish
Bhatt.
22) Do not cache ipv4 routing failures, otherwise if the sysctl for
forwarding is subsequently enabled this won't be seen. From
Nicolas Cavallari"

Pull sparc update from David Miller:
"Two changes:
1) It makes no sense to execute a VTOC partition table request in the
Sun virtual block device driver and fail to load if it doesn't
succeed because a) we don't use the result at all and b) it won't
succeed if there is an EFI partition on the disk, for example.
We read the partition table via the normal means in the block layer
anyways, so this is really completely useless, so just remove it.
From Dwight Engen.
2) Hook up new bpf system call"
