net: pcs: xpcs: convert to mdio_device

Unify the 2 existing PCS drivers (lynx and xpcs) by doing a similar
thing on probe, which is to have a *_create function that takes a
struct mdio_device * given by the caller, and builds a private PCS
structure around that.

This changes stmmac to hold only a pointer to the xpcs, as opposed to
the full structure. This will be used in the next patch when struct
mdio_xpcs_ops is removed. Currently a pointer to struct mdio_xpcs_ops
is used as a shorthand to determine whether the port has an XPCS or not.
We can do the same now with the mdio_xpcs_args pointer.

net: pcs: xpcs: make the checks related to the PHY interface mode stateless

The operating mode of the driver is currently to populate its
struct mdio_xpcs_args::supported and struct mdio_xpcs_args::an_mode
statically in xpcs_probe(), based on the passed phy_interface_t,
and work with those.

However this is not the operation that phylink expects from a PCS
driver, because the port might be attached to an SFP cage that triggers
changes of the phy_interface_t dynamically as one SFP module is
unpluggged and another is plugged.

To migrate towards that model, the struct mdio_xpcs_args should not
cache anything related to the phy_interface_t, but just look up the
statically defined, const struct xpcs_compat structure corresponding to
the detected PCS OUI/model number.

So we delete the "supported" and "an_mode" members of struct
mdio_xpcs_args, and add the "id" structure there (since the ID is not
expected to change at runtime).

Since xpcs->supported is used deep in the code in _xpcs_config_aneg_c73(),
we need to modify some function headers to pass the xpcs_compat from all
callers. In turn, the xpcs_compat is always supplied externally to the
xpcs module:
- Most of the time by phylink
- In xpcs_probe() it is needed because xpcs_soft_reset() writes to
  MDIO_MMD_PCS or to MDIO_MMD_VEND2 depending on whether an_mode is clause
  37 or clause 73. In order to not introduce functional changes related
  to when the soft reset is issued, we continue to require the initial
  phy_interface_t argument to be passed to xpcs_probe() so we can pass
  this on to xpcs_soft_reset().
- stmmac_open() wants to know whether to call stmmac_init_phy() or not,
  and for that it looks inside xpcs->an_mode, because the clause 73
  (backplane) AN modes supposedly do not have a PHY. Because we moved
  an_mode outside of struct mdio_xpcs_args, this is now no longer
  directly possible, so we introduce a helper function xpcs_get_an_mode()
  which protects the data encapsulation of the xpcs module and requires
  a phy_interface_t to be passed as argument. This function can look up
  the appropriate compat based on the phy_interface_t.

net: pcs: xpcs: there is only one PHY ID

The xpcs driver has an apparently inadequate structure for the actual
hardware it drives.

These defines and the xpcs_probe() function would suggest that there is
one PHY ID per supported PHY interface type, and the driver simply
validates whether the mode it should operate in (the argument of
xpcs_probe) matches what the hardware is capable of:

#define SYNOPSYS_XPCS_USXGMII_ID 0x7996ced0
#define SYNOPSYS_XPCS_10GKR_ID 0x7996ced0
#define SYNOPSYS_XPCS_XLGMII_ID 0x7996ced0
#define SYNOPSYS_XPCS_SGMII_ID 0x7996ced0
#define SYNOPSYS_XPCS_MASK 0xffffffff

but that is not the case, because upon closer inspection, all the above
4 PHY ID definitions are in fact equal.

So it is the same XPCS that is compatible with all 4 sets of PHY
interface types.

This change introduces an array of struct xpcs_compat which is populated
by the single struct xpcs_id instance. It also eliminates the bogus
defines for multiple Synopsys XPCS PHY IDs and replaces them with a
single XPCS_ID, which better reflects the way in which the hardware
operates.

Because we are touching this area of the code anyway, the new array of
struct xpcs_compat, as well as the array of xpcs_id, have been moved
towards the end of the file, since they are variable declarations not
definitions. If whichever of struct xpcs_compat or struct xpcs_id need
to gain a function pointer member in the future, it is easier to
reference functions (no forward declarations needed) if we have the
const variable declarations at the end of the file.

====================
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

devlink: Introduce rate nodes

Implement support for DEVLINK_CMD_RATE_{NEW|DEL} commands that are used
to create and delete devlink rate nodes. Add new attribute
DEVLINK_ATTR_RATE_NODE_NAME that specify node name string. The node name
is an alphanumeric identifier. No valid node name can be a devlink port
index, eg. decimal number. Extend devlink ops with new callbacks
rate_node_{new|del}() and rate_node_tx_{share|max}_set() to allow
supporting drivers to implement ports rate grouping and setting tx rate
of rate nodes through devlink.
Expose devlink_rate_nodes_destroy() function to allow vendor driver do
proper cleanup of internally allocated resources for the nodes if the
driver goes down or due to any other reasons which requires nodes to be
destroyed.
Disallow moving device from switchdev to legacy mode if any node exists
on that device. User must explicitly delete nodes before switching mode.

Example:

$ devlink port function rate add netdevsim/netdevsim10/group1

$ devlink port function rate set netdevsim/netdevsim10/group1 \
        tx_share 10mbit tx_max 100mbit

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             +------+---+
                  +----------+              |
                  | tc_merge +--------+     |
                  +----------+        v     v

                               |
                               |
                               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.

Changes since v2:
- nfp: flower-ct: add zone table entry when handling pre/post_ct flows
    Fixed another docstring. Should finally have the patch check

Cleanup is happening when all the tables are cleared up and prints
a warning traceback as this is not expected in the final version.
At this point we are not actually returning success for the offload,

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:

   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

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:

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.

- revert tcf_vlan_get_fill_size change: total size calculation may race vs dump

v2 -> v3:
- Push assumes that the priority is being set

will be changed to:

ethertype 802.1Q (0x8100), vlan 300, p 4, ethertype IPv4

although the user has intended to have p == 0.

Marvell Prestera Switchdev initial updates for firmware version 3.0

has such changes like:

    - initial routing support

    - LAG support

    - events interrupt handling changes

Changes just make able to work with new firmware version but

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.
