Hashing the peer key was introduced for AF_INET, but gcc
warns about the rxrpc_peer_hash_key function returning uninitialized
data for any other value of srx->transport.family:

net/rxrpc/peer_object.c:57:15: error: 'p' may be used uninitialized in this function [-Werror=maybe-uninitialized]
Assuming that nothing else can be set here, this changes the

mlxsw: Preparation for IPv4 router
Ido says:
This series prepares the driver for IPv4 router support. The router follow-up
patches are available at: https://github.com/jpirko/linux_mlxsw/tree/net-next_queue
Patches 1-9 simplify the netdevice notification block and also add several
checks during PRECHANGEUPPER events against topologies that aren't supported by
the device. This will ensure L3 interfaces are only configured on top of
valid netdevs.
Patches 10-13 contain trivial changes required for the introduction of a generic
FID struct - currently only used for vFIDs - in patch 14. Making the FID
struct generic will allow us to easily associate the underlying FIDs with
their L3-counterparts - Router interfaces (RIFs):
FID Type | Used by | RIF Type
--------------------------------------------------------
FID | The VLAN-aware bridge | VLAN
vFID | VLAN-unaware bridges | FID
rFID | non-bridged netdevs (follow-up) | Sub-port
Obligatory ASCII art to visualize the above:
A.B.C.D
+
| FID RIF
+
br0 E.F.G.H
+ +
| | VLAN RIF
+---------+---------+ +
| | br1.W
| vFID | +
| | |
vPort +-+-+ +-+-+ +
swXpY.Z | | | | br1
+-+-+ +-+-+ +
| | FID=W |

| | | |
+---+---+ +---+-+-+ +---+---+
| | | | | |
| | | | | |
| | | | | |
+-------+ +-------+ +-------+
swXpY
Patches 15-16 further generalize the struct by exploiting the fact that the
FID is a shared resource among ports. Each FID type is assigned a 'leave'
function that is invoked based on CHANGEUPPER events and takes care of the
necessary clean-up.
Patches 17-22 build upon the previous patches and use the FID struct for the
VLAN-aware bridge and take care of cleaning up FID resources in the 'leave'
functions. For now, these are only FDB records, but later on we'll have to
remove the RIFs associated with these FIDs, which will in turn take care of
routes and neighbours clean-up.
The last patch adds debug prints that proved very useful during the
development of this series.
Tested with the existing L2 recipes:

There are situations in which a vPort is destroyed while still holding
references to device's resources such as FIDs and FDB records. This can
happen, for example, when a VLAN device is deleted while still being
bridged.
Instead of trying to make sure vPort destruction is invoked when it no
longer uses device's resources, just free them upon destruction. This
simplifies the code, as we no longer need to take different situations
into account when events are received - cleanup is taken care of in one
place.

FDB entries are learned using {Port / LAG ID, FID} and therefore should
be flushed whenever a port (vPort) leaves its FID (vFID).
However, when the bridge port is a LAG device (or a VLAN device on top),
then FDB flushing is conditional. Ports removed from such LAG
configurations must not trigger flushing, as other ports might still be
members in the LAG and therefore the bridge port is still active.
The decision whether to flush or not was previously computed in the
netdevice notification block, but in order to flush the entries when a
port leaves its FID this decision should be computed there.
Strip the notification block from this logic and instead move it to one
FDB flushing function that is invoked from both the FID / vFID leave
functions.
When port isn't member in LAG, FDB flushing should always occur.
Otherwise, it should occur only when the last port (vPort) member in the
LAG leaves the FID (vFID).
This will allow us - in the next patch - to simplify the cleanup code
paths that are hit whenever the topology above the port netdevs changes.

In a very similar way to the vFIDs, make the first 4K FIDs - used in the
VLAN-aware bridge - use the new FID struct.
Upon first use of the FID by any of the ports do the following:
1) Create the FID
2) Setup a matching flooding entry
3) Create a mapping for the FID
Unlike vFIDs, upon creation of a FID we always create a global
VID-to-FID mapping, so that ports without upper vPorts can use it
instead of creating an explicit {Port, VID} to FID mapping.
When a port leaves a FID the reverse is performed. Whenever the FID's
reference count reaches zero the FID is deleted along with the global
mapping.
The per-FID struct will later allow us to configure L3 interfaces on top
of the VLAN-aware bridge.

Up until now we had a dedicated struct only for vFIDs, but before
introducing support for L3 interfaces we need to make it generic and
use it for all three types of FIDs:
1) FIDs - 0..4K-1, used for the VLAN-aware bridge
2) vFIDs - 4K..15K-1, used for VLAN-unaware bridges
3) rFIDs - 15K..16K-1, used to direct traffic to / from the router in
the device. Will be introduced later in the series.
The three types of L3 interfaces - Router InterFaces, RIFs - that will
be introduced correspond to the three types of FIDs and are configured
using them. Therefore, we'll need to store the links between them as
well as a reference count on the underlying FID, so that the
corresponding RIF will be destroyed when it reaches zero.
Note that the lower 0.5K vFIDs are currently used for for non-bridged
netdevs, so that traffic could be flooded to the CPU port. However, when
rFIDs will be introduced we'll no longer need these and they too will be
used for VLAN-unaware bridges.
Make the vFID struct generic by renaming it and some of its fields. FIDs
will be converted to use it later in the series.

This will allow us to use a compatible chip info to describe how to
access the SMI device and its switch ID register at probe time.
For the legacy probe, we fix the compatible info to 88E6085. For the
MDIO probe, we will use the compatible info from the device node data.
All patches are reviewed.
Changes since v4:
- fix debug printing (was 'val' instead of '*val')
Changes since v3 [3]:
- better register access abstraction using the chip structure
Changes since v2 [2]:
- do not guess compatible model in legacy probe
- add low level SMI API using a chip structure
- allocate before probe and detection
- add 3 cosmetic patches
Changes since v1 [1]:
- merge style fix from Ben Dooks
- add Acked-by/Reviewed-by tags
- drop one compatible string per model
- detect the SMI device based on the compatible info
- add an SMI ops structure

When the SMI address of the switch chip is zero, the chip assumes to be
the only one on the SMI master bus and thus responds to all its known
SMI devices addresses (port registers, Global2, etc.)
When its SMI address is not zero, some chips (e.g. 88E6352) use an
indirect access through two SMI Command and Data registers.
Other models (e.g. 88E6060) using less than 16 internal SMI addresses
always use a direct access.
Add a capability flag to describe chips supporting the (indirect)
Multi-chip Addressing Mode, and a low-level API to access the registers
via SMI.
Other accesses (like Ethernet management frames) may be added later.
