99976fc084 brcmfmac: fix wrong num_different_channels when mchan feature enabled
When the device/firmware supports multi-channel, it can have P2P
connection and regular connection with AP simultaneous. In this case,
the num_different_channels in wiphy info was not correct when firmware
supports multi-channel (The iw wiphy# info showed "#channels <= 1" in
interface combinations). It caused association failed and error message
"CTRL-EVENT-FREQ-CONFLICT error" in wpa_supplicant when P2P GO interface
was running at the same time.
The root cause is that the num_different_channels was always overridden
to 1 in brcmf_setup_ifmodes even multi-channel was enabled.
We correct the logic by moving num_different_channels setting forward.

38db25aeda Merge branch 'Update-DSAs-FDB-API-and-perform-switchdev-cleanup'
Arkadi Sharshevsky says:

====================
Update DSA's FDB API and perform switchdev cleanup

The patchset adds support for configuring static FDB entries via the
switchdev notification chain. The current method for FDB configuration
uses the switchdev's bridge bypass implementation. In order to support
this legacy way and to perform the switchdev cleanup, the implementation
is moved inside DSA.

The DSA drivers cannot sync the software bridge with hardware learned
entries and use the switchdev's implementation of bypass FDB dumping.
Because they are the only ones using this functionality, the fdb_dump
implementation is moved from switchdev code into DSA.

Finally after this changes a major cleanup in switchdev can be done.

Please see individual patches for patch specific change logs.
v1->v2
- Split MDB/vlan dump removal into core/driver removal.

v2->v3
- The self implementation for FDB add/del is moved inside DSA.

29ab586c3d net: switchdev: Remove bridge bypass support from switchdev
Currently the bridge port flags, vlans, FDBs and MDBs can be offloaded
through the bridge code, making the switchdev's SELF bridge bypass
implementation to be redundant. This implies several changes:
- No need for dump infra in switchdev, DSA's special case is handled
  privately.
- Remove obj_dump from switchdev_ops.
- FDBs are removed from obj_add/del routines, due to the fact that they
  are offloaded through the bridge notification chain.
- The switchdev_port_bridge_xx() and switchdev_port_fdb_xx() functions
  can be removed.

37b8da1a3c net: dsa: Move FDB add/del implementation inside DSA
Currently DSA uses switchdev's implementation of FDB add/del ndos. This
patch moves the implementation inside DSA in order to support the legacy
way for static FDB configuration.

c9eb3e0f87 net: dsa: Add support for learning FDB through notification
Add support for learning FDB through notification. The driver defers
the hardware update via ordered work queue. In case of a successful
FDB add a notification is sent back to bridge.

In case of hw FDB del failure the static FDB will be deleted from
the bridge, thus, the interface is moved to down state in order to
indicate inconsistent situation.

2acf4e6a89 net: dsa: Remove switchdev dependency from DSA switch notifier chain
Currently, the switchdev objects are embedded inside the DSA notifier
info. This patch removes this dependency. This is done as a preparation
stage before adding support for learning FDB through the switchdev
notification chain.

1b6dd556c3 net: dsa: Remove prepare phase for FDB
The prepare phase for FDB add is unneeded because most of DSA devices
can have failures during bus transactions (SPI, I2C, etc.), thus, the
prepare phase cannot guarantee success of the commit stage.

The support for learning FDB through notification chain, which will be
introduced in the following patches, will provide the ability to notify
back the bridge about successful offload.

In order to support FDB add/del to be on a notifier chain the slave
API need to be changed to be switchdev independent.
