As the mvpp2 driver is growing, move this driver to a dedicated

Since this driver has a lot of register defines and structure
definitions, it can benefit from having all of this into a dedicated
header file, named mvpp2.h.

A good chunk of the mvpp2 code is dedicated to Header Parser handling, so
we introduce mvpp2_prs.h where all Header Parser definitions are located,
and mvpp2_prs.c containing the related code.

In the same way, mvpp2_cls.h and mvpp2_cls.c are created to contain
Classifier and RSS related code.

The former 'mvpp2.c' file is renamed 'mvpp2_main.c' so that we can keep
the driver binary named 'mvpp2'.

This commit is only about spliting the driver into multiple files and

====================
net: bridge: Notify about bridge VLANs

In commit 946a11e7408e ("mlxsw: spectrum_span: Allow bridge for gretap
mirror"), mlxsw got support for offloading mirror-to-gretap such that
the underlay packet path involves a bridge. In that case, the offload is
also influenced by PVID setting of said bridge. However, changes to VLAN
configuration of the bridge itself do not generate switchdev
notifications, so there's no mechanism to prod mlxsw to update the
offload when these settings change.

In this patchset, the problem is resolved by distributing the switchdev
notification SWITCHDEV_OBJ_ID_PORT_VLAN also for configuration changes
on bridge VLANs. Since stacked devices distribute the notification to
lower devices, such event eventually reaches the driver, which can
determine whether it's a bridge or port VLAN by inspecting orig_dev.

To keep things consistent, the newly-distributed notifications observe
the same protocol as the existing ones: dual prepare/commit, with
-EOPNOTSUPP indicating lack of support, even though there's currently
nothing to prepare for and nothing to support. Correspondingly, all
switchdev drivers have been updated to return -EOPNOTSUPP for bridge
VLAN notifications.

In patches #1 and #2, the code base is changed to support the following
additions: functions br_switchdev_port_vlan_add() and
br_switchdev_port_vlan_del() are introduced to simplify sending
notifications; and br_vlan_add_existing() is introduced to later make it
simpler to add error-handling code for the case of configuring a
preexisting VLAN on bridge CPU port.

In patches #3-#6, respectively for mlxsw, rocker, DSA and DPAA2 ethsw,
the new notifications (which are not enabled yet) are ignored to
maintain the current behavior.

In patch #7, the notification is actually enabled.

In patch #8, mlxsw is changed to update offloads of mirror-to-gre also
for bridge-related notifications.

Changes from v3 to v4:

- In patch #1, separate variable declarations from program logic.
- Add patch #2.
- In patch #7, add error handling around a newly-introduced call to
  br_switchdev_port_vlan_add().
- Rephrase commit messages of patches #3-#6 to explain motivation for
  the change.

Changes from v2 to v3:

- Add a fallback definition for br_switchdev_port_obj_add() and
  br_switchdev_port_obj_del() when !CONFIG_NET_SWITCHDEV.

Changes from v1 to v2:

- Rename br_switchdev_port_obj_add() and br_switchdev_port_obj_del() to
  br_switchdev_port_vlan_add() and br_switchdev_port_vlan_del(), and
  move from br_vlan.c to br_switchdev.c.

schedule respin during the prepare stage: there's no real difference one
way or another.

This fixes the problem that mirror-to-gretap offload wouldn't adapt to

At this point, skb->data is same with tcp_hdr() as tcp header has not

====================
net: Add address attribute to control metric of prefix route

For use cases such as VRR (Virtual Router Redundancy) interface managers
want efficient control over the order of prefix routes when multiple
interfaces have addresses with overlapping/duplicate subnets.

Currently, if two interfaces have addresses in the same subnet, the order
of the prefix route entries is determined by the order in which the
addresses are assigned or the links brought up. Any actions like cycling
an interface up and down changes that order. This set adds a new attribute
for addresses to allow a user to specify the metric of the prefix route
associated with an address giving interface managers better and more
efficient control of the order of prefix routes.

Patches 1-3 refactor IPv6 address add functions to pass an ifa6_config
struct. The functions currently have a long list of arguments and adding
the metric just makes it worse. Because of the overall diff size in
moving the arguments to a struct, the change is done in stages to make
it easier to review starting with the bottom function and pushing the
struct up to callers in each successive patch.

Patch 4 introduces the new attribute.

Patches 5 and 6 add support for the new attribute to IPv4 and IPv6
addresses.

Patch 7 adds a set of test cases.

Patch 8 adds support to iproute2

Merge branch 'nfp-abm-RED-MQ-qdisc-offload'

Jakub Kicinski says:

====================
nfp: abm: RED/MQ qdisc offload

This is second batch of advanced buffer management nfp driver
changes.  This series adds the qdisc offload.  Support for
a very simple subset of RED qdisc offload is added as needed
for DCTCP ECN marking (min and max thresholds set to the same
value).

The first two patches fix glitches introduced by the previous
series.  We have to be careful about phys_port_name handling,
because VFs share the same code path, and some user space may
get confused by the names we chose.

Since unlike previous offloads we can report the queue backlog
both in bytes and packets we need to adjust how statistics are
added up in the core (patch 6).

There are some extra statistics we want to expose which don't
fit into TC stats, namely counts of packets which have been fast-
-forwarded without getting enqueued because there was no
contention and number of packets that were ever queued (sum of
all momentary backlogs).  We expose those through ethtool stats
(patches 8 and 9).

Remaining 5 patches add MQ offload - to be able to set different
configurations on different queues.  Representors are made multi-
-queue and we add offload support to MQ.  MQ stats are added up
before calling ->dump qdiscs on the children, and therefore don't
include updated offload values.  To avoid clearly incorrect stats
MQ is made to also request stats update from offloads.  This way
we can correct the diff at the driver level.
