Test mirror-to-gretap with bridge in UL
This patchset adds more tests to the mirror-to-gretap suite where bridge
is present in the underlay. Specifically it adds tests for bridge VLAN
handling, FDB, and bridge port STP status.
In patches #1-#3, the codebase is refactored to support the new tests.
In patch #4, an STP test is added to the mirroring library, that will
later be called from bridge tests.
In patches #5-#8, the test for mirror-to-gretap with an 802.1q bridge in
underlay is adapted and more tests are added.
In patch #9, an STP test is added to the test suite for mirror-to-gretap
with an 802.1d bridge in underlay.

As the mvpp2 driver is growing, move this driver to a dedicated
directory and split it into several files.
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
doesn't introduce any new function, feature or fix besides removing
'static' keywords when needed.

allocates the maximum size expected for all possible types and adds
sanity-checks at both registration and usage to make sure nothing gets

.slave_maxtype and manually counting the enums:
slave_maxtype (max 33):
IFLA_BRPORT_MAX 33
IFLA_BOND_SLAVE_MAX 9
maxtype (max 45):
IFLA_BOND_MAX 28
IFLA_BR_MAX 45

IFLA_VRF_MAX 2
IFLA_VTI_MAX 7
IFLA_VXLAN_MAX 28

This additionally changes maxtype and slave_maxtype fields to unsigned,
since they're only ever using positive values.

net: bridge: Notify about bridge VLANs
In commit 946a11e740 ("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.

Since there's no special support for the bridge events, the driver
returns -EOPNOTSUPP, and thus the commit never happens. Therefore
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
changes in bridge vlan configuration right away and another notification
would have to arrive for mlxsw to catch up.
