In commit 9f5bcfe93315 ("ath10k: silence firmware file probing
warnings") the firmware loading was changed from request_firmware() to
request_firmware_direct() to silence some warnings in case it fails.
request_firmware_direct() directly searches in the file system only and
does not send a hotplug event to user space in case it could not find
the firmware directly.
In LEDE we use a user space script to extract the calibration data from
the flash memory which gets triggered by the hotplug event. This way the
firmware gets extracted from some vendor specific partition when the
driver requests this firmware. This mechanism does not work any more
after this change.

In napi_poll, the budget number is used to control the amount of packets
we should handle per poll to balance the resource in the system.
In the list of the amsdu packets reception, we check if there is budget
count left and handle the complete list of the packets, that it will have
chances the very last list will over the budget leftover.
So adding one more parameter - budget_left, this would help while
traversing the list to avoid handling more than the budget given.

In conjunction with crypto offload [1], removing the ESP trailer by
hardware can potentially improve the performance by avoiding (1) a
cache miss incurred by reading the nexthdr field and (2) the necessity
to calculate the csum value of the trailer in order to keep skb->csum
valid.
This patch introduces the changes to the xfrm stack and merely serves
as an infrastructure. Subsequent patch to mlx5 driver will put this to
a good use.

mlx5-updates-2017-08-31 (GRE Offloads support)
This series provides the support for MPLS RSS and GRE TX offloads and
RSS support.
The first patch from Gal and Ariel provides the mlx5 driver support for
ConnectX capability to perform IP version identification and matching in
order to distinguish between IPv4 and IPv6 without the need to specify the
encapsulation type, thus perform RSS in MPLS automatically without
specifying MPLS ethertyoe. This patch will also serve for inner GRE IPv4/6
classification for inner GRE RSS.
2nd patch from Gal, Adds the TX offloads support for GRE tunneled packets,
by reporting the needed netdev features.
3rd patch from Gal, Adds GRE inner RSS support by creating the needed device
resources (Steering Tables/rules and traffic classifiers) to Match GRE traffic
and perform RSS hashing on the inner headers.

Fix crash in linux PF driver when BARs have been cleared/de-programmed;
fail early init (prior to mapping BARs) if the BAR0 or
BAR1 registers are zero.
This situation can arise when the PF is added to a VM (PCI pass-through),
then a PF FLR is issued (in the VM). After this occurs, the BAR registers
will be zero. If we attempt to load the PF driver in the host
(after VM has been shutdown), the host can reset.

Introduce a new flow table and indirect TIRs which are used to hash the
inner packet headers of GRE tunneled packets.
When a GRE tunneled packet is received, the TTC flow table will match
the new IPv4/6->GRE rules which will forward it to the inner TTC table.
The inner TTC is similar to its counterpart outer TTC table, but
matching the inner packet headers instead of the outer ones (and does
not include the new IPv4/6->GRE rules).
The new rules will not add steering hops since they are added to an
already existing flow group which will be matched regardless of this
patch. Non GRE traffic will not be affected.
The inner flow table will forward the packet to inner indirect TIRs
which hash the inner packet and thus result in RSS for the tunneled
packets.

This change adds the ability for flow steering to classify IPv4/6
packets with MPLS tag (Ethertype 0x8847 and 0x8848) as standard IP
packets and hit IPv4/6 classification steering rules.
Since IP packets with MPLS tag header have MPLS ethertype, they
missed the IPv4/6 ethertype rule and ended up hitting the default
filter forwarding all the packets to the same single RQ (No RSS).
Since our device is able to look past the MPLS tag and identify the
next protocol we introduce this solution which replaces ethertype
matching by the device's capability to perform IP version
identification and matching in order to distinguish between IPv4 and
IPv6.
Therefore, when driver is performing flow steering configuration on the
device it will use IP version matching in IP classified rules instead
of ethertype matching which will cause relevant MPLS tagged packets to
hit this rule as well.
If the device doesn't support IP version matching the driver will fall back
to use legacy ethertype matching in the steering as before.

IPv6 packet may carry more than one extension header, and IPv6 nodes must
accept and attempt to process extension headers in any order and occurring
any number of times in the same packet. Hence, there should be no
assumption that Segment Routing extension header is to appear immediately
after the IPv6 header.
Moreover, section 4.1 of RFC 8200 gives a recommendation on the order of
appearance of those extension headers within an IPv6 packet. According to
this recommendation, Segment Routing extension header should appear after
Hop-by-Hop and Destination Options headers (if they present).
This patch fixes the get_srh(), so it gets the segment routing header
regardless of its position in the chain of the extension headers in IPv6
packet, and makes sure that the IPv6 routing extension header is of Type 4.

net: mvpp2: comphy configuration
This series, following up the one one the GoP/MAC configuration, aims at
stopping to depend on the firmware/bootloader configuration when using
the PPv2 engine. With this series the PPv2 driver does not need to rely
on a previous configuration, and dynamic reconfiguration while the
kernel is running can be done (i.e. switch one port from SGMII to 10G,
or the opposite). A port can now be configured in a different mode than
what's done in the firmware/bootloader as well.
The series first contain patches in the generic PHY framework to support
what is called the comphy (common PHYs), which is an h/w block providing
PHYs that can be configured in various modes ranging from SGMII, 10G
to SATA and others. As of now only the SGMII and 10G modes are
supported by the comphy driver.
Then patches are modifying the PPv2 driver to first add the comphy
initialization sequence (i.e. calls to the generic PHY framework) and to
then take advantage of this to allow dynamic reconfiguration (i.e.
configuring the mode of a port given what's connected, between sgmii and
10G). Note the use of the comphy in the PPv2 driver is kept optional
(i.e. if not described in dt the driver still as before an relies on the
firmware/bootloader configuration).
Finally there are dt/defconfig patches to describe and take advantage of
this.
This was tested on a range of devices: 8040-db, 8040-mcbin and 7040-db.
@Dave: the dt patches should go through the mvebu tree (patches 9-13).
Thanks!
Antoine
Since v3:
- Now use of_phy_simple_xlate() to retrieve the phy.
- Added an owner in the phy_ops structure.
- Now allow the module to be selected with COMPILE_TEST.
- Removed unused parameter in the comphy set_mode functions.
- Added Kishon Acked-by in patch 1.
Since v2:
- Kept the link mode enforcement.
- Removed the netif_running() check.
- Reworded the "dynamic reconfiguration of the PHY mode" commit log.
- Added one patch not to force the GMAC autoneg parameters when using
the XLG MAC.
Since v1:
- Updated the mode settings variable name in the comphy driver to
have 'cp110' in it.
- Documented the PHY cell argument in the dt documentation.
- New patch adding comphy phandles for the 7040-db board.
- Checked if the carrier_on/off functions were needed. They are.

This patch adds logic to reconfigure the comphy/GoP/MAC when the link
state is updated at runtime. This is very useful on boards where many
link speed are supported: depending on what is negotiated the PPv2
driver will automatically reconfigures the link between the PHY and the
MAC.

various modes by other controllers (network, SATA ...). These common

either at boot time, or when the system runs to switch the mode used.

used.

net/sched: Improve getting objects by indexes
Using current TC code, it is very slow to insert a lot of rules.
In order to improve the rules update rate in TC,
we introduced the following two changes:
1) changed cls_flower to use IDR to manage the filters.
2) changed all act_xxx modules to use IDR instead of
a small hash table
But IDR has a limitation that it uses int. TC handle uses u32.
To make sure there is no regression, we add several new IDR APIs
to support unsigned long.

Typically, each TC filter has its own action. All the actions of the
same type are saved in its hash table. But the hash buckets are too
small that it degrades to a list. And the performance is greatly
affected. For example, it takes about 0m11.914s to insert 64K rules.
If we convert the hash table to IDR, it only takes about 0m1.500s.
The improvement is huge.
But please note that the test result is based on previous patch that
cls_flower uses IDR.

Currently, all filters with the same priority are linked in a doubly
linked list. Every filter should have a unique handle. To make the
handle unique, we need to iterate the list every time to see if the
handle exists or not when inserting a new filter. It is time-consuming.
For example, it takes about 5m3.169s to insert 64K rules.
This patch changes cls_flower to use IDR. With this patch, it
takes about 0m1.127s to insert 64K rules. The improvement is huge.
But please note that in this testing, all filters share the same action.
If every filter has a unique action, that is another bottleneck.
Follow-up patch in this patchset addresses that.

v8->v9: Fix comments from David - Remove the CFLAG rule. Change the way
rmnet devices are freed. Instead of using a workqueue to unregister devices
individually, go through the list and free all devices within the rtnl_lock().
v9->v10: Actually fix the locking as mentioned by David. The locking scheme is
mentioned in a comment in rmnet_config.c. Change comment near MAP type
definition as mentioned by Dan. Refactor some code.
v10->v11: Allow RMNET to compile as a module as mentioned by David

RmNet driver provides a transport agnostic MAP (multiplexing and
aggregation protocol) support in embedded module. Module provides
virtual network devices which can be attached to any IP-mode
physical device. This will be used to provide all MAP functionality
on future hardware in a single consistent location.
