Merge branch 'devlink-rate-objects'
Dmytro Linkin says:
====================
devlink: rate objects API
Resending without RFC.
Currently kernel provides a way to change tx rate of single VF in
switchdev mode via tc-police action. When lots of VFs are configured
management of theirs rates becomes non-trivial task and some grouping
mechanism is required. Implementing such grouping in tc-police will bring
flow related limitations and unwanted complications, like:
- tc-police is a policer and there is a user request for a traffic
shaper, so shared tc-police action is not suitable;
- flows requires net device to be placed on, means "groups" wouldn't
have net device instance itself. Taking into the account previous
point was reviewed a sollution, when representor have a policer and
the driver use a shaper if qdisc contains group of VFs - such approach
ugly, compilated and misleading;
- TC is ingress only, while configuring "other" side of the wire looks
more like a "real" picture where shaping is outside of the steering
world, similar to "ip link" command;
According to that devlink is the most appropriate place.
This series introduces devlink API for managing tx rate of single devlink
port or of a group by invoking callbacks (see below) of corresponding
driver. Also devlink port or a group can be added to the parent group,
where driver responsible to handle rates of a group elements. To achieve
all of that new rate object is added. It can be one of the two types:
- leaf - represents a single devlink port; created/destroyed by the
driver and bound to the devlink port. As example, some driver may
create leaf rate object for every devlink port associated with VF.
Since leaf have 1to1 mapping to it's devlink port, in user space it is
referred as pci/<bus_addr>/<port_index>;
- node - represents a group of rate objects; created/deleted by request
from the userspace; initially empty (no rate objects added). In
userspace it is referred as pci/<bus_addr>/<node_name>, where node name
can be any, except decimal number, to avoid collisions with leafs.
devlink_ops extended with following callbacks:
- rate_{leaf|node}_tx_{share|max}_set
- rate_node_{new|del}
- rate_{leaf|node}_parent_set
KAPI provides:
- creation/destruction of the leaf rate object associated with devlink
port
- destruction of rate nodes to allow a vendor driver to free allocated
resources on driver removal or due to the other reasons when nodes
destruction required
UAPI provides:
- dumping all or single rate objects
- setting tx_{share|max} of rate object of any type
- creating/deleting node rate object
- setting/unsetting parent of any rate object
Added devlink rate object support for netdevsim driver
Issues/open questions:
- Does user need DEVLINK_CMD_RATE_DEL_ALL_CHILD command to clean all
children of particular parent node? For example:
$ devlink port function rate flush netdevsim/netdevsim10/group
- priv pointer passed to the callbacks is a source of bugs; in leaf case
driver can embed rate object into internal structure and use
container_of() on it; in node case it cannot be done since nodes are
created from userspace
v1->v2:
- fixed kernel-doc for devlink_rate_leaf_{create|destroy}()
- s/func/function/ for all devlink port command occurences
v2->v3:
- devlink:
- added devlink_rate_nodes_destroy() function
- netdevsim:
- added call of devlink_rate_nodes_destroy() function

Merge branch 'nfp-ct-offload'
Simon Horman says:
====================
Introduce conntrack offloading to the nfp driver
Louis Peens says:
This is the first in a series of patches to offload conntrack
to the nfp. The approach followed is to flatten out three
different flow rules into a single offloaded flow. The three
different flows are:
1) The rule sending the packet to conntrack (pre_ct)
2) The rule matching on +trk+est after a packet has been through
conntrack. (post_ct)
3) The rule received via callback from the netfilter (nft)
In order to offload a flow we need a combination of all three flows, but
they could be added/deleted at different times and in different order.
To solve this we save potential offloadable CT flows in the driver,
and every time we receive a callback we check against these saved flows
for valid merges. Once we have a valid combination of all three flows
this will be offloaded to the NFP. This is demonstrated in the diagram
below.
+-------------+ +----------+
| pre_ct flow +--------+ | nft flow |
+-------------+ v +------+---+

Offload to nfp
This series is only up to the point of the pre_ct and post_ct
merges into the tc_merge. Follow up series will continue
to add the nft flows and merging of these flows with the result
of the pre_ct and post_ct merged flows.

====================
net: qualcomm: rmnet: Enable Mapv5
This series introduces the MAPv5 packet format.
Patch 0 documents the MAPv4/v5.
Patch 1 introduces the MAPv5 and the Inline checksum offload for RX/Ingress.
Patch 2 introduces the MAPv5 and the Inline checksum offload for TX/Egress.
A new checksum header format is used as part of MAPv5.For RX checksum offload,
the checksum is verified by the HW and the validity is marked in the checksum
header of MAPv5. For TX, the required metadata is filled up so hardware can
compute the checksum.
v1->v2:
- Fixed the compilation errors, warnings reported by kernel test robot.
- Checksum header definition is expanded to support big, little endian
formats as mentioned by Jakub.
v2->v3:
- Fixed compilation errors reported by kernel bot for big endian flavor.
v3->v4:
- Made changes to use masks instead of C bit-fields as suggested by Jakub/Alex.
v4->v5:
- Corrected checkpatch errors and warnings reported by patchwork.
v5->v6:
- Corrected the bug identified by Alex and incorporated all his comments.
v6->v7:
- Removed duplicate inclusion of linux/bitfield.h in rmnet_map_data.c
v7->v8:
- Have addressed comments given by JAkub on v7 patches.
- As suggested by Jakub, skb_cow_head() is used instead of expanding
the head directly. This is now done in rmnet_map_egress_handler().

====================
net/sched: act_vlan: Fix modify to allow 0
Currently vlan modification action checks existence of vlan priority by
comparing it to 0. Therefore it is impossible to modify existing vlan
tag to have priority 0.
For example, the following tc command will change the vlan id but will
not affect vlan priority:
tc filter add dev eth1 ingress matchall action vlan modify id 300 \
priority 0 pipe mirred egress redirect dev eth2
The incoming packet on eth1:
ethertype 802.1Q (0x8100), vlan 200, p 4, ethertype IPv4
will be changed to:
ethertype 802.1Q (0x8100), vlan 300, p 4, ethertype IPv4
although the user has intended to have p == 0.
The fix is to add tcfv_push_prio_exists flag to struct tcf_vlan_params
and rely on it when deciding to set the priority.
The same flag is used to avoid dumping unset vlan priority.
Change Log:
v3 -> v4:
- revert tcf_vlan_get_fill_size change: total size calculation may race vs dump
v2 -> v3:
- Push assumes that the priority is being set
- tcf_vlan_get_fill_size accounts for priority existence

create a common enetc_pf_to_port helper"), enetc_pf_to_port was coded up
to return -1 in case the passed PCIe device does not have a recognized
BDF.
Make sure the -1 value is checked by the callers, to appease static
checkers.

====================
Marvell Prestera Switchdev initial updates for firmware version 3.0
This series adds minimal support for firmware version 3.0 which
has such changes like:
- initial routing support
- LAG support
- events interrupt handling changes
Changes just make able to work with new firmware version but
supported features in driver will be added later.
New firmware version was recently merged into linux-firmware tree.
Added ability of loading previous fw major version if the latest one
is missing, also add support for previous FW ABI.
PATCH -> RFC:
1) Load previous fw version if the latest one is missing (suggested by Andrew Lunn)
2) Add support for previous FW ABI version (suggested by Andrew Lunn)
RFC v2:
1) Get rid of automatic decrementing of
major version but hard code it.
2) Print error message with file path if
previous FW could not be loaded.

- an adaptation of the driver to the new "ethernet-ports" OF node name
- an adaptation of the driver to support more than 1 SGMII port
- a generalization of the supported phy_interface_t values per port
- an adaptation to encode SPEED_10, SPEED_100, SPEED_1000 into the

- a consolidation of the PHY interface type used for RGMII and another
one for the API exposed for sja1105_dynamic_config_read()

net: dsa: sja1105: some table entries are always present when read dynamically
The SJA1105 has a static configuration comprised of a number of tables
with entries. Some of these can be read and modified at runtime as well,
through the dynamic configuration interface.
As a careful reader can notice from the comments in this file, the
software interface for accessing a table entry through the dynamic
reconfiguration is a bit of a no man's land, and varies wildly across
switch generations and even from one kind of table to another.
I have tried my best to come up with a software representation of a
'common denominator' SPI command to access a table entry through the
dynamic configuration interface:
struct sja1105_dyn_cmd {
bool search;
u64 valid; /* must be set to 1 */
u64 rdwrset; /* 0 to read, 1 to write */
u64 errors;
u64 valident; /* 0 if entry is invalid, 1 if valid */
u64 index;
};
Relevant to this patch is the VALIDENT bit, which for READ commands is
populated by the switch and lets us know if we're looking at junk or at
a real table entry.
In SJA1105, the dynamic reconfiguration interface for management routes
has notably not implemented the VALIDENT bit, leading to a workaround to
ignore this field in sja1105_dynamic_config_read(), as it will be set to
zero, but the data is valid nonetheless.
In SJA1110, this pattern has sadly been abused to death, and while there
are many more tables which can be read back over the dynamic config
interface compared to SJA1105, their handling isn't in any way more
uniform. Generally speaking, if there is a single possible entry in a
given table, and loading that table in the static config is mandatory as
per the documentation, then the VALIDENT bit is deemed as redundant and
more than likely not implemented.
So it is time to make the workaround more official, and add a bit to the
flags implemented by dynamic config tables. It will be used by more
tables when SJA1110 support arrives.
