This patch ensures that VLAN traffic on the default VID will go to the
corresponding VLAN device if it exists. To do this, mask the rx_ring VID
if we have an active VLAN on that VID.
For this to work correctly, we need to update fm10k_process_skb_fields
to correctly mask off the VLAN_PRIO_MASK bits and compare them
separately, otherwise we incorrectly compare the priority bits with the
cleared flag. This also happens to fix a related bug where having
priority bits set causes us to incorrectly classify traffic.

If we store the sw_vid at reset of PF, then we accidentally prevent the
VF from receiving the message to update its default VID. This only
occurs if the VF is created before the PF has come up, which is the
standard way of creating VFs when using the module parameter.
This fixes an issue where we request the incorrect MAC/VLAN
combinations, and prevents us from accidentally reporting some frames as
VLAN tagged.

This change adds the MAC address to the list of values recorded on driver

us to track the value should a card be replaced in a system.

This is useful in cases where we connect to a slot at Gen3, but the slot
is behind a bus which only connected at Gen2. This generally only
happens when a PCIe switch is in the sequence of devices, and can be
very confusing when you see slow performance with no obvious cause.
I am aware this patch has a few lines that break 80 characters, but
there does not seem to be a readable way to format them to less than 80
characters. Suggestions welcome.

This allows us to correctly add a VLAN even if it matches our default
VID. However, we don't want to remove the VID rules once that VLAN is
deleted. Correctly remove the stack layers information of the VLAN, but
then return to forwarding that VID as untagged frames. If we deleted the
VID rules here, we would begin dropping traffic due to VLAN membership
violations.

The service task reads some registers as part of its normal routine,
even while the interface is down. Normally this is ok. However, during
suspend we have disabled the PCI device. Due to this, registers will
read in the same way as a surprise-remove event. Disable the service
task while we suspend, and re-enable it after we resume. If we don't do
this, the device could be UP when you suspend and come back from resume
as closed (since fm10k closes the device when it gets a surprise
remove).

This patch updates the lowest limit for adaptive interrupt interrupt
moderation to roughly 12K interrupts per second.
The way I came about reaching 12K as the desired interrupt rate is by
testing with UDP flows. Specifically I had a simple test that ran a
netperf UDP_STREAM test at varying sizes. What I found was as the packet
sizes increased the performance fell steadily behind until we were only
able to receive at ~4Gb/s with a message size of 65507. A bit of digging
found that we were dropping packets for the socket in the network stack,
and looking at things further what I found was I could solve it by increasing
the interrupt rate, or increasing the rmem_default/rmem_max. What I found was
that when the interrupt coalescing resulted in more data being processed
per interrupt than could be stored in the socket buffer we started losing
packets and the performance dropped. So I reached 12K based on the
following math.
rmem_default = 212992
skb->truesize = 2994
212992 / 2994 = 71.14 packets to fill the buffer
packet rate at 1514 packet size is 812744pps
71.14 / 812744 = 87.9us to fill socket buffer
From there it was just a matter of choosing the interrupt rate and
providing a bit of wiggle room which is why I decided to go with 12K
interrupts per second as that uses a value of 84us.
The data below is based on VM to VM over a direct assigned ixgbe interface.
The test run was:
netperf -H <ip> -t UDP_STREAM"
Socket Message Elapsed Messages CPU Service
Size Size Time Okay Errors Throughput Util Demand
bytes bytes secs # # 10^6bits/sec % SS us/KB
Before:
212992 65507 60.00 1100662 0 9613.4 10.89 0.557
212992 60.00 473474 4135.4 11.27 0.576

212992 60.00 974132 8508.3 11.69 0.598
Using bare metal the data is similar but not as dramatic as the throughput
increases from about 8.5Gb/s to 9.5Gb/s.

When the .remove() callback for a PF is called, SR-IOV support for the
device is disabled, which requires unbinding and removing the VFs.
The VFs may be in-use either by the host kernel or userspace, such as
assigned to a VM through vfio-pci. In this latter case, the VFs may
be removed either by shutting down the VM or hot-unplugging the
devices from the VM. Unfortunately in the case of a Windows 2012 R2
guest, hot-unplug is broken due to the ordering of the PF driver
teardown. Disabling SR-IOV prior to unregister_netdev() avoids this
issue.

Many commonly used functions like getifaddrs() invoke RTM_GETLINK
to dump the interface information, and do not need the
the AF_INET6 statististics that are always returned by default
from rtnl_fill_ifinfo().
Computing the statistics can be an expensive operation that impacts
scaling, so it is desirable to avoid this if the information is
not needed.
This patch adds a the RTEXT_FILTER_SKIP_STATS extended info flag that
can be passed with netlink_request() to avoid statistics computation
for the ifinfo path.

In DRA72x EVM, by default slave 1 is connected to the onboard
phy, but slave 2 pins are also muxed with video input module
which is controlled by pcf857x gpio and currently to select slave
0 to connect to phy gpio hogging is used, but with
omap2plus_defconfig the pcf857x gpio is built as module. So when
using NFS on DRA72x EVM, board doesn't boot as gpio hogging do
not set proper gpio state to connect slave 0 to phy as it is
built as module and you do not see any errors for not setting
gpio and just mentions dhcp reply not got.
To solve this issue, introducing "mode-gpios" in DT when gpio
based muxing is required. This will throw a warning when gpio
get fails and returns probe defer. When gpio-pcf857x module is
installed, cpsw probes again and ethernet becomes functional.
Verified this on DRA72x with pcf as module and ramdisk.

net: dsa: mv88e6xxx: improve ATU move operations
This patchset completes the set of available Address Translation Unit
operations.
These Marvell switches have 4 operations to flush or (re)move, all or

just a particular one.
The first 3 patches introduce a generic _mv88e6xxx_atu_flush_move
function. The 4 remaining patches update a few FID operations in the
driver on setup, when a port join or leave a VLAN, or change state.
This is a step forward improving the hardware bridging support in DSA

These Marvell switches have 4 operations to flush or (re)move, all or

The value of the EntryState bits will determine if the operation is

Pull blk-cg updates from Jens Axboe:
"A bit later in the cycle, but this has been in the block tree for a a
while. This is basically four patchsets from Tejun, that improve our
buffered cgroup writeback. It was dependent on the other cgroup
changes, but they went in earlier in this cycle.
Series 1 is set of 5 patches that has cgroup writeback updates:
- bdi_writeback iteration fix which could lead to some wb's being
skipped or repeated during e.g. sync under memory pressure.
- Simplification of wb work wait mechanism.
- Writeback tracepoints updated to report cgroup.
Series 2 is is a set of updates for the CFQ cgroup writeback handling:
cfq has always charged all async IOs to the root cgroup. It didn't
have much choice as writeback didn't know about cgroups and there
was no way to tell who to blame for a given writeback IO.
writeback finally grew support for cgroups and now tags each
writeback IO with the appropriate cgroup to charge it against.
This patchset updates cfq so that it follows the blkcg each bio is
tagged with. Async cfq_queues are now shared across cfq_group,
which is per-cgroup, instead of per-request_queue cfq_data. This
makes all IOs follow the weight based IO resource distribution
implemented by cfq.
- Switched from GFP_ATOMIC to GFP_NOWAIT as suggested by Jeff.
- Other misc review points addressed, acks added and rebased.
Series 3 is the blkcg policy cleanup patches:
This patchset contains assorted cleanups for blkcg_policy methods
and blk[c]g_policy_data handling.
- alloc/free added for blkg_policy_data. exit dropped.
- alloc/free added for blkcg_policy_data.
- blk-throttle's async percpu allocation is replaced with direct
allocation.
- all methods now take blk[c]g_policy_data instead of blkcg_gq or
blkcg.
And finally, series 4 is a set of patches cleaning up the blkcg stats
handling:
blkcg's stats have always been somwhat of a mess. This patchset
tries to improve the situation a bit.
- The following patches added to consolidate blkcg entry point and
blkg creation. This is in itself is an improvement and helps
colllecting common stats on bio issue.
- per-blkg stats now accounted on bio issue rather than request
completion so that bio based and request based drivers can behave
the same way. The issue was spotted by Vivek.
- cfq-iosched implements custom recursive stats and blk-throttle
implements custom per-cpu stats. This patchset make blkcg core
support both by default.
- cfq-iosched and blk-throttle keep track of the same stats
multiple times. Unify them"

Pull late ARM SoC updates from Kevin Hilman:
"This is a collection of a few late fixes and other misc stuff that had
dependencies on things being merged from other trees.
The bulk of the changes are for samsung/exynos SoCs for some changes
that needed a few minor reworks so ended up a bit late. The others
are mainly for qcom SoCs: a couple fixes and some DTS updates"

Due to some recent changes in
drm_helper_probe_single_connector_modes_merge_bits(), old custom modes
were not being pruned properly. In current kernels,
drm_mode_validate_basic() is called to sanity-check each mode in the
list. If the sanity-check passes, the mode's status gets set to to
MODE_OK. In older kernels this check was not done, so old custom modes
would still have a status of MODE_UNVERIFIED at this point, and would
therefore be pruned later in the function.
As a result of this new behavior, the list of modes for a device always
includes every custom mode ever configured for the device, with the
largest one listed first. Since desktop environments usually choose the
first preferred mode when a hotplug event is emitted, this had the
result of making it very difficult for the user to reduce the size of
the display.
The qxl driver did implement the mode_valid connector function, but it
was empty. In order to restore the old behavior where old custom modes
are pruned, we implement a proper mode_valid function for the qxl
driver. This function now checks each mode against the last configured
custom mode and the list of standard modes. If the mode doesn't match
any of these, its status is set to MODE_BAD so that it will be pruned as
expected.
