of_net: add NVMEM support to of_get_mac_address
Many embedded devices have information such as MAC addresses stored
inside NVMEMs like EEPROMs and so on. Currently there are only two
drivers in the tree which benefit from NVMEM bindings.
Adding support for NVMEM into every other driver would mean adding a lot
of repetitive code. This patch allows us to configure MAC addresses in
various devices like ethernet and wireless adapters directly from
of_get_mac_address, which is already used by almost every driver in the
tree.
Predecessor of this patch which used directly MTD layer has originated
in OpenWrt some time ago and supports already about 497 use cases in 357
device tree files.

100GbE Intel Wired LAN Driver Updates 2019-05-04
This series contains updates to the ice driver only.
Jesse updated the driver to make more functions consistent in their use
of a local variable for vsi->back. Updates the driver to use bit fields
when possible to avoid wasting lots of storage space to store single bit
values. Optimized the driver to be more memory efficient by moving
structure members around that are not in are hot path.
Michal updates the driver to disable the VF if malicious device driver
(MDD) event is detected by the hardware. Adds checks to validate the
messages coming from the VF driver. Tightens up the sniffing of the
driver so that transmit traffic so that VF's cannot see what is on other
VSIs.
Tony fixed the driver so that receive stripping state won't change every
time transmit insertion is changed. Cleanup the __always_unused
attribute, now that the variable is being used. Fixed the function
which evaluates setting of features to ensure that can evaluate and set
multiple features in a single function call.
Akeem fixes the driver so that we do not attempt to remove a VLAN filter
that does not exist. Adds support for adding a ethertype based filter
rule on VSI and describe it in a very long run-on sentence. :-)
Bruce cleans up static analysis warnings by removing a local variable
initialization that is not needed.
Brett makes the allocate/deallocate more consistent in all the driver
flows for VSI q_vectors. In addition, makes setting/getting coalesce
settings more consistent throughout the driver.

Bluetooth: Ignore CC events not matching the last HCI command
This commit makes the kernel not send the next queued HCI command until
a command complete arrives for the last HCI command sent to the
controller. This change avoids a problem with some buggy controllers
(seen on two SKUs of QCA9377) that send an extra command complete event
for the previous command after the kernel had already sent a new HCI
command to the controller.
The problem was reproduced when starting an active scanning procedure,
where an extra command complete event arrives for the LE_SET_RANDOM_ADDR
command. When this happends the kernel ends up not processing the
command complete for the following commmand, LE_SET_SCAN_PARAM, and
ultimately behaving as if a passive scanning procedure was being
performed, when in fact controller is performing an active scanning
procedure. This makes it impossible to discover BLE devices as no device
found events are sent to userspace.
This problem is reproducible on 100% of the attempts on the affected
controllers. The extra command complete event can be seen at timestamp
27.420131 on the btmon logs bellow.

====================
wireless-drivers-next patches for 5.2
Most likely the last patchset of new feature for 5.2, and this time we
have quite a lot of new features. Most obvious being rtw88 from
Realtek which supports RTL8822BE and RTL8822CE 802.11ac devices. We
have also new hardware support for existing drivers and improvements.
There's one conflict in iwlwifi, my example conflict resolution below.
Major changes:
iwlwifi
* bump the 20000-series FW API version
* work on new hardware continues
* RTT confidence indication support for Fine Timing Measurement (FTM)
* an improvement in HE (802.11ax) rate-scaling
* add command version parsing from the fimware TLVs
* add support for a new WoWLAN patterns firmware API
rsi
* add support for rs9116
mwifiex
* add support for SD8987
brcmfmac
* add quirk for ACEPC T8 and T11 mini PCs
rt2x00
* add RT3883 support
qtnfmac
* fix debugfs interface to support multiple cards
rtw88
* new driver
mt76
* share more code across drivers
* add support for MT7615 chipset
* rework DMA API
* tx/rx performance optimizations
* use NAPI for tx cleanup on mt76x02
* AP mode support for USB devices
* USB stability fixes
* tx power handling fixes for 76x2
* endian fixes

size = sizeof(struct foo) + count * sizeof(struct boo);

genetlink: do not validate dump requests if there is no policy
Unlike do requests, dump genetlink requests now perform strict validation
by default even if the genetlink family does not set policy and maxtype
because it does validation and parsing on its own (e.g. because it wants to
allow different message format for different commands). While the null
policy will be ignored, maxtype (which would be zero) is still checked so
that any attribute will fail validation.

tipc: fix missing Name entries due to half-failover
TIPC link can temporarily fall into "half-establish" that only one of
the link endpoints is ESTABLISHED and starts to send traffic, PROTOCOL
messages, whereas the other link endpoint is not up (e.g. immediately
when the endpoint receives ACTIVATE_MSG, the network interface goes
down...).
This is a normal situation and will be settled because the link
endpoint will be eventually brought down after the link tolerance time.
However, the situation will become worse when the second link is
established before the first link endpoint goes down,
For example:
1. Both links <1A-2A>, <1B-2B> down
2. Link endpoint 2A up, but 1A still down (e.g. due to network
disturbance, wrong session, etc.)
3. Link <1B-2B> up
4. Link endpoint 2A down (e.g. due to link tolerance timeout)
5. Node B starts failover onto link <1B-2B>
==> Node A does never start link failover.
When the "half-failover" situation happens, two consequences have been
observed:
a) Peer link/node gets stuck in FAILINGOVER state;
b) Traffic or user messages that peer node is trying to failover onto
the second link can be partially or completely dropped by this node.
The consequence a) was actually solved by commit
c140eb166d68 ("tipc:
fix failover problem"), but that commit didn't cover the b). It's due
to the fact that the tunnel link endpoint has never been prepared for a
failover, so the 'l->drop_point' (and the other data...) is not set
correctly. When a TUNNEL_MSG from peer node arrives on the link,
depending on the inner message's seqno and the current 'l->drop_point'
value, the message can be dropped (- treated as a duplicate message) or
processed.
At this early stage, the traffic messages from peer are likely to be
NAME_DISTRIBUTORs, this means some name table entries will be missed on
the node forever!
The commit resolves the issue by starting the FAILOVER process on this
node as well. Another benefit from this solution is that we ensure the
link will not be re-established until the failover ends.

the link has 100Mbps instead of 1Gbps. Reason is that another OS has

the PHY advertises is what it did when hibernating.
Easiest way to do this is removing state PHY_RESUMING. Instead always

net: phy: improve pause handling
When probing the phy device we set sym and asym pause in the "supported"
bitmap (unless the PHY tells us otherwise). However we don't know yet
whether the MAC supports pause. Simply copying phy->supported to
phy->advertising will trigger advertising pause, and that's not
what we want. Therefore add phy_advertise_supported() that copies all
modes but doesn't touch the pause bits.
In phy_support_(a)sym_pause we shouldn't set any bits in the supported
bitmap because we may set a bit the PHY intentionally disabled.
Effective pause support should be the AND-combined PHY and MAC pause
capabilities. If the MAC supports everything, then it's only relevant
what the PHY supports. If MAC supports sym pause only, then we have to
clear the asym bit in phydev->supported.
Copy the pause flags only and don't touch the modes, because a driver
may have intentionally removed a mode from phydev->advertising.

100GbE Intel Wired LAN Driver Updates 2019-05-02
This series contains updates to the ice driver only.
Anirudh introduces the framework to store queue specific information in
the VSI queue contexts. This will allow future changes to update the
structure to hold queue specific information.
Akeem adds additional check so that if there is no queue to disable when
attempting to disable a queue, return a configuration error without
acquiring the lock. Fixed an issue with non-trusted VFs being able to
add more than the permitted number of VLANs.
Bruce removes unreachable code and updated the function to return void
since it would never return anything but success.
Brett provides most of the changes in the series, starting with reducing
the scope of the error variable used and improved the debug message if
we fail to configure the receive queue. Updates the driver to use a
macro instead of using the same 'for' loop throughout the driver which
helps with readability. Fixed an issue where users were led to believe
they could set rx-usecs-high value, yet the changes to this value would
not stick because it was not yet implemented to allow changes to this
value, so implement the missing code to change the value. Found we had
unnecessary wait when disabling queues, so remove it. I,proved a
wasteful addition operation in our hot path by adding a member to the
ice_q_vector structure and the necessary changes to use the member which
stores the calculated vector hardware index. Refactored the link event
flow to make it cleaner and more clear.
Maciej updates the array index when stopping transmit rings, so that
process every ring the VSI, not just the rings in a given transmit
class.
Paul adds support for setting 52 byte RSS hash keys.
Md Fahad cleaned up a runtime change to the PFINT_OICR_ENA register,
since the interrupt handlers will handle resetting the bit, if
necessary.

Jake cleans up a check that is not needed and was producing a warning in
GCC 8.
Harshitha fixes a misleading message by ensuring that a success message
is only printed on the host side when the promiscuous mode change has
been successful.
Stefan Assmann adds the vendor id and device id to the dmesg log entry
during probe to help with bug reports when lspci output may not be
available.
Alice and Piotr add recovery mode support in the i40e driver, which is
needed for migrating from a structured to a flat firmware image.
v2: Removed patch 1 "i40e: replace switch-statement to speed-up
retpoline-enabled builds" from the series since it is no longer
needed. Also updated the last patch in the series that introduces
recovery mode support, to include a more detailed patch description
and removed code not intended for the upstream kernel.

i40e: Introduce recovery mode support
This patch introduces "recovery mode" to the i40e driver. It is
part of a new Any2Any idea of upgrading the firmware. In this
approach, it is required for the driver to have support for
"transition firmware", that is used for migrating from structured
to flat firmware image. In this new, very basic mode, i40e driver
must be able to handle particular IOCTL calls from the NVM Update
Tool and run a small set of AQ commands.
These additional AQ commands are part of the interface used by
the NVMUpdate tool. The NVMUpdate tool contains all of the
necessary logic to reference these new AQ commands. The end user
experience remains the same, they are using the NVMUpdate tool to
update the NVM contents.
