This is a bit messy right now, there are functions for both,
but then gen1 function can actually deal with both gen1 and
gen2, due to the confusion about use_tfh/gen2 cleaned up in
the previous patch.
Fix the common paths to call the right functions and remove
handling of gen2 from the gen1 function.

There's no reason to warn here, it's not an internal consistency
issue, we even use this to check if the device is dead, and if it
read_mem() returns an error that's either because grab NIC access
or memory allocation failed, both of which are already noisy.
Just remove the warning entirely.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct cfg80211_tid_config.

Time Averaged SAR (TAS) tracks the amount of transmit power over a
period of time and adjusts the power accordingly. Two thresholds are
used to determine when to increase or reduce transmit power: Dynamic
Power Reduction (DPR) on/off. Compared to Static SAR, which has a
constant transmit power, TAS can improve the user experience or
range extension.
TAS can be enabled through BIOS, and the driver will evaluate
Realtek ACPI DSM with RTW89_ACPI_DSM_FUNC_TAS_EN to determine
whether TAS should be enabled.

The current implementation seems to reinvent what `kstrtoul` already does
in terms of functionality and error handling. Remove uses of `simple_strtoul()`
in favor of `kstrtoul()`.
There is the following note at `lib/vsprintf.c:simple_strtoull()` which
further backs this change:
| * This function has caveats. Please use kstrtoull (or kstrtoul) instead.
And here, simple_str* are explicitly deprecated [3].
This patch also removes an instance of the deprecated `strncpy` which helps [2].
Compile tested only.

Add a test case for IPv6 source address delete.
As David suggested, add tests:
- Single device using src address
- Two devices with the same source address
- VRF with single device using src address
- VRF with two devices using src address
As Ido points out, in IPv6, the preferred source address is looked up in
the same VRF as the first nexthop device. This will give us similar results
to IPv4 if the route is installed in the same VRF as the nexthop device, but
not when the nexthop device is enslaved to a different VRF. So add tests:
- src address and nexthop dev in same VR
- src address and nexthop device in different VRF
The link local address delete logic is different from the global address.
It should only affect the associate device it bonds to. So add tests cases
for link local address testing.
Here is the test result:
IPv6 delete address route tests
Single device using src address
TEST: Prefsrc removed when src address removed on other device [ OK ]
Two devices with the same source address
TEST: Prefsrc not removed when src address exist on other device [ OK ]
TEST: Prefsrc removed when src address removed on all devices [ OK ]
VRF with single device using src address
TEST: Prefsrc removed when src address removed on other device [ OK ]
VRF with two devices using src address
TEST: Prefsrc not removed when src address exist on other device [ OK ]
TEST: Prefsrc removed when src address removed on all devices [ OK ]
src address and nexthop dev in same VRF
TEST: Prefsrc removed from VRF when source address deleted [ OK ]
TEST: Prefsrc in default VRF not removed [ OK ]
TEST: Prefsrc not removed from VRF when source address exist [ OK ]
TEST: Prefsrc in default VRF removed [ OK ]
src address and nexthop device in different VRF
TEST: Prefsrc not removed from VRF when nexthop dev in diff VRF [ OK ]
TEST: Prefsrc not removed in default VRF [ OK ]
TEST: Prefsrc removed from VRF when nexthop dev in diff VRF [ OK ]
TEST: Prefsrc removed in default VRF [ OK ]

TEST: Prefsrc not removed when delete ll addr from other dev [ OK ]
TEST: Prefsrc removed when delete ll addr [ OK ]
TEST: Prefsrc not removed when delete ll addr from other dev [ OK ]
TEST: Prefsrc removed even ll addr still exist on other dev [ OK ]

After deleting an IPv6 address on an interface and cleaning up the
related preferred source entries, it is important to ensure that all
routes associated with the deleted address are properly cleared. The
current implementation of rt6_remove_prefsrc() only checks the preferred
source addresses bound to the current device. However, there may be
routes that are bound to other devices but still utilize the same
preferred source address.
To address this issue, it is necessary to also delete entries that are
bound to other interfaces but share the same source address with the
current device. Failure to delete these entries would leave routes that
are bound to the deleted address unclear. Here is an example reproducer
(I have omitted unrelated routes):
+ ip link add dummy1 type dummy
+ ip link add dummy2 type dummy
+ ip link set dummy1 up
+ ip link set dummy2 up
+ ip addr add 1:2:3:4::5/64 dev dummy1
+ ip route add 7:7:7:0::1 dev dummy1 src 1:2:3:4::5
+ ip route add 7:7:7:0::2 dev dummy2 src 1:2:3:4::5
+ ip -6 route show
1:2:3:4::/64 dev dummy1 proto kernel metric 256 pref medium
7:7:7::1 dev dummy1 src 1:2:3:4::5 metric 1024 pref medium
7:7:7::2 dev dummy2 src 1:2:3:4::5 metric 1024 pref medium
+ ip addr del 1:2:3:4::5/64 dev dummy1
+ ip -6 route show
7:7:7::1 dev dummy1 metric 1024 pref medium
7:7:7::2 dev dummy2 src 1:2:3:4::5 metric 1024 pref medium
As Ido reminds, in IPv6, the preferred source address is looked up in
the same VRF as the first nexthop device, which is different with IPv4.
So, while removing the device checking, we also need to add an
ipv6_chk_addr() check to make sure the address does not exist on the other
devices of the rt nexthop device's VRF.
After fix:
+ ip addr del 1:2:3:4::5/64 dev dummy1
+ ip -6 route show
7:7:7::1 dev dummy1 metric 1024 pref medium
7:7:7::2 dev dummy2 metric 1024 pref medium

As the initial commit 1a01727676a8 ("selftests: Add VRF route leaking
tests") said, the IPv6 MTU test fails as source address selection
picking ::1. Every time we run the selftest this one report failed.
There seems not much meaning to keep reporting a failure for 3 years
that no one plan to fix/update. Let't just skip this one first. We can
add it back when the issue fixed.

Setting IP_RECVERR and IPV6_RECVERR options to zero currently
purges the socket error queue, which was probably not expected
for zerocopy and tx_timestamp users.
I discovered this issue while preparing commit 6b5f43ea0815
("inet: move inet->recverr to inet->inet_flags"), I presume this
change does not need to be backported to stable kernels.
Add skb_errqueue_purge() helper to purge error messages only.

The user ports use RSGMII, but we don't have that, and DT doesn't
specify a phy interface mode, so phylib defaults to GMII. These support
1G, 100M and 10M with flow control. It is unknown whether asymetric
pause is supported at all speeds.
The CPU port uses MII/GMII/RGMII/REVMII by hardware pin strapping,
and support speeds specific to each, with full duplex only supported
in some modes. Flow control may be supported again by hardware pin
strapping, and theoretically is readable through a register but no
information is given in the datasheet for that.
So, we do a best efforts - and be lenient.

Currently any error during render leads to output an empty file.
That is quite annoying when using tools/net/ynl/ynl-regen.sh
which git greps files with content of "YNL-GEN.." and therefore ignores
empty files. So once you fail to regen, you have to checkout the file.
Avoid that by rendering to a temporary file first, only at the end
copy the content to the actual destination.
