The binding docs requires for SMI-connected devices that the switch
must have a child node named "mdio" and with a compatible string of
"realtek,smi-mdio". Meanwile, for MDIO-connected switches, the binding
docs only requires a child node named "mdio".
This patch changes the driver to use the common denominator for both
interfaces, looking for the MDIO node by name, ignoring the compatible
string.

Previously, the interface modules realtek-smi and realtek-mdio served as
a platform and an MDIO driver, respectively. Each interface module
redundantly specified the same compatible strings for both variants and
referenced symbols from the variants.
Now, each variant module has been transformed into a unified driver
serving both as a platform and an MDIO driver. This modification
reverses the relationship between the interface and variant modules,
with the variant module now utilizing symbols from the interface
modules.

====================
Remove expired routes with a separated list of routes.
This patchset is resent due to previous reverting. [1]
FIB6 GC walks trees of fib6_tables to remove expired routes. Walking a tree
can be expensive if the number of routes in a table is big, even if most of
them are permanent. Checking routes in a separated list of routes having
expiration will avoid this potential issue.
Background
==========
The size of a Linux IPv6 routing table can become a big problem if not
managed appropriately. Now, Linux has a garbage collector to remove
expired routes periodically. However, this may lead to a situation in
which the routing path is blocked for a long period due to an
excessive number of routes.
For example, years ago, there is a commit c7bb4b89033b ("ipv6: tcp:
drop silly ICMPv6 packet too big messages"). The root cause is that
malicious ICMPv6 packets were sent back for every small packet sent to
them. These packets add routes with an expiration time that prompts
the GC to periodically check all routes in the tables, including
permanent ones.
Why Route Expires
=================
Users can add IPv6 routes with an expiration time manually. However,
the Neighbor Discovery protocol may also generate routes that can
expire. For example, Router Advertisement (RA) messages may create a
default route with an expiration time. [RFC 4861] For IPv4, it is not
possible to set an expiration time for a route, and there is no RA, so
there is no need to worry about such issues.
Create Routes with Expires
==========================
You can create routes with expires with the command.
For example,
ip -6 route add 2001:b000:591::3 via fe80::5054:ff:fe12:3457 \
dev enp0s3 expires 30
The route that has been generated will be deleted automatically in 30
seconds.
GC of FIB6
==========
The function called fib6_run_gc() is responsible for performing
garbage collection (GC) for the Linux IPv6 stack. It checks for the
expiration of every route by traversing the trees of routing
tables. The time taken to traverse a routing table increases with its
size. Holding the routing table lock during traversal is particularly
undesirable. Therefore, it is preferable to keep the lock for the
shortest possible duration.
Solution
========
The cause of the issue is keeping the routing table locked during the
traversal of large trees. To solve this problem, we can create a separate
list of routes that have expiration. This will prevent GC from checking
permanent routes.
Result
======
We conducted a test to measure the execution times of fib6_gc_timer_cb()
and observed that it enhances the GC of FIB6. During the test, we added
permanent routes with the following numbers: 1000, 3000, 6000, and
9000. Additionally, we added a route with an expiration time.
Here are the average execution times for the kernel without the patch.
- 120020 ns with 1000 permanent routes
- 308920 ns with 3000 ...
- 581470 ns with 6000 ...
- 855310 ns with 9000 ...
The kernel with the patch consistently takes around 14000 ns to execute,
regardless of the number of permanent routes that are installed.
Majro changes from v5:
- Force syncrhonize GC before query expired routes with
"sysctl -wq net.ipv6.route.flush=1".
Major changes from v4:
- Fix the comment of fib6_add_gc_list().
Major changes from v3:
- Move the checks of f6i->fib6_node to fib6_add_gc_list().
- Make spin_lock_bh() and spin_unlock_bh() stands out.
- Explain the reason of the changes in the commit message of the
patch 4.
Major changes from v2:
- Refactory the boilerplate checks in the test case.
- check_rt_num() and check_rt_num_clean()
Major changes from v1:
- Reduce the numbers of routes (5) in the test cases to work with
slow environments. Due to the failure on patchwork.
- Remove systemd related commands in the test case.
Major changes from the previous patchset [2]:
- Split helpers.
- fib6_set_expires() -> fib6_set_expires() and fib6_add_gc_list().
- fib6_clean_expires() -> fib6_clean_expires() and

- Fix rt6_add_dflt_router() to avoid racing of setting expires.
- Remove unnecessary calling to fib6_clean_expires() in

- Add test cases of toggling routes between permanent and temporary
and handling routes from RA messages.
- Clean up routes by deleting the existing device and adding a new

Make the decision to set or clean the expires of a route based on the
RTF_EXPIRES flag, rather than the value of the "expires" argument.
This patch doesn't make difference logically, but make inet6_addr_modify()
and modify_prefix_route() consistent.
The function inet6_addr_modify() is the only caller of
modify_prefix_route(), and it passes the RTF_EXPIRES flag and an expiration
value. The RTF_EXPIRES flag is turned on or off based on the value of
valid_lft. The RTF_EXPIRES flag is turned on if valid_lft is a finite value
(not infinite, not 0xffffffff). Even if valid_lft is 0, the RTF_EXPIRES
flag remains on. The expiration value being passed is equal to the
valid_lft value if the flag is on. However, if the valid_lft value is
infinite, the expiration value becomes 0 and the RTF_EXPIRES flag is turned
off. Despite this, modify_prefix_route() decides to set the expiration
value if the received expiration value is not zero. This mixing of infinite
and zero cases creates an inconsistency.

Pass the duration of a lifetime (in seconds) to the function
rt6_add_dflt_router() so that it can properly set the expiration time.
The function ndisc_router_discovery() is the only one that calls
rt6_add_dflt_router(), and it will later set the expiration time for the
route created by rt6_add_dflt_router(). However, there is a gap of time
between calling rt6_add_dflt_router() and setting the expiration time in
ndisc_router_discovery(). During this period, there is a possibility that a
new route may be removed from the routing table. By setting the correct
expiration time in rt6_add_dflt_router(), we can prevent this from
happening. The reason for setting RTF_EXPIRES in rt6_add_dflt_router() is
to start the Garbage Collection (GC) timer, as it only activates when a
route with RTF_EXPIRES is added to a table.

====================
net: phy: Introduce PHY Package concept
Idea of this big series is to introduce the concept of PHY package in DT
and give PHY drivers a way to derive the base address from DT.
The concept of PHY package is nothing new and is already a thing in the
kernel with the API phy_package_join/leave/read/write.
What is currently lacking is describing this in DT and better reference
a base address to calculate offset from.
In the scenario of a PHY package where multiple address are used and
there isn't a way to get the base address of the PHY package from some
regs, getting the information from DT is the only way.
A possible example to this problem is this:
ethernet-phy-package@0 {
compatible = "qcom,qca8075-package";
#address-cells = <1>;
#size-cells = <0>;
reg = <0>;
qcom,package-mode = "qsgmii";
ethernet-phy@1 {
reg = <1>;
};
phy4: ethernet-phy@4 {
reg = <4>;
};
};
The mdio parse functions are changed to address for this additional
special node, the function is changed to simply detect this node and
search also in this. (we match the node name to be "ethernet-phy-package")
PHY driver can then use introduced helper of_phy_package_join to join the
PHY to the PHY package and derive the base address from DT.
Changes v7:
- Rebase on top of net-next
- Add Reviewed-by tag for DT patch
- Change tx-driver-strength to tx-drive-strength
- Drop driver reference in DT

- Back to absolute PHY implementation
- Correctly drop refcount for node on error condition and on PHY leave
- Drop DT include patch in favor for 3 boolean vendor property

description

- Rework fiber read status to use more generic function
- Split qca808x LED generalization patch to permit easier review
- Correctly return -EINVAL with wrong data passed to vendor property
- Drop removing LED ops for qca807x PHY driver with gpio-controller
Changes v5:
- Rebase on top of net-next
- Change implementation to base addr + offset in subnode
- Adapt to all the changes and cleanup done to at803x
Changes v4:

- Drop of autojoin support and rework to simple helper
- Rework PHY driver to the new implementation
- Add compatible for qca807x package
- Further cleanup patches

- Detach patch that can be handled separately (phy_package_mmd,
phy_package extended)
- Rework code to new simplified implementation with base addr + offset

The np value is filled only with of_phy_package_join if a valid PHY

Add support for scanning PHY in PHY package nodes. PHY packages nodes
are just container for actual PHY on the MDIO bus.
Their PHY address defined in the PHY package node are absolute and
reflect the address on the MDIO bus.
mdio_bus.c and of_mdio.c is updated to now support and parse also
PHY package subnode by checking if the node name match
"ethernet-phy-package".
As PHY package reg is mandatory and each PHY in the PHY package must
have a reg, every invalid PHY Package node is ignored and will be
skipped by the autoscan fallback.

Document ethernet PHY package nodes used to describe PHY shipped in
bundle of 2-5 PHY. The special node describe a container of PHY that
share common properties. This is a generic schema and PHY package
should create specialized version with the required additional shared
properties.
Example are PHY packages that have some regs only in one PHY of the
package and will affect every other PHY in the package, for example
related to PHY interface mode calibration or global PHY mode selection.
The PHY package node MUST declare the base address used by the PHY driver
for global configuration by calculating the offsets of the global PHY
based on the base address of the PHY package.
Each reg of the PHYs defined in the PHY package node is absolute and
describe the real address of the Ethernet PHY on the bus.

udpgso regression test configures routing and device MTU directly through
uAPI (Netlink, ioctl) to do its job. While there is nothing wrong with it,
it takes more effort than doing it from shell.
Looking forward, we would like to extend the udpgso regression tests to
cover the EIO corner case [1], once it gets addressed. That will require a
dummy device and device feature manipulation to set it up. Which means more
Netlink code.
So, in preparation, pull out network configuration into the shell script
part of the test, so it is easily extendable in the future.
Also, because it now easy to setup routing, add a second local IPv6
address. Because the second address is not managed by the kernel, we can
"replace" the corresponding local route with a reduced-MTU one. This
unblocks the disabled "ipv6 connected" test case. Add a similar setup for
IPv4 for symmetry.
