====================
net: fib_rules: Add DSCP selector support
Currently, the kernel rejects IPv4 FIB rules that try to match on the
upper three DSCP bits:
# ip -4 rule add tos 0x1c table 100
# ip -4 rule add tos 0x3c table 100
Error: Invalid tos.
The reason for that is that historically users of the FIB lookup API
only populated the lower three DSCP bits in the TOS field of the IPv4
flow key ('flowi4_tos'), which fits the TOS definition from the initial
IPv4 specification (RFC 791).
This is not very useful nowadays and instead some users want to be able
to match on the six bits DSCP field, which replaced the TOS and IP
precedence fields over 25 years ago (RFC 2474). In addition, the current
behavior differs between IPv4 and IPv6 which does allow users to match
on the entire DSCP field using the TOS selector.
Recent patchsets made sure that callers of the FIB lookup API now
populate the entire DSCP field in the IPv4 flow key. Therefore, it is
now possible to extend FIB rules to match on DSCP.
This is done by adding a new DSCP attribute which is implemented for
both IPv4 and IPv6 to provide user space programs a consistent behavior
between both address families.
The behavior of the old TOS selector is unchanged and IPv4 FIB rules
using it will only match on the lower three DSCP bits. The kernel will
reject rules that try to use both selectors.
Patch #1 adds the new DSCP attribute but rejects its usage.
Patches #2-#3 implement IPv4 and IPv6 support.
Patch #4 allows user space to use the new attribute.
Patches #5-#6 add selftests.

The FIB rule TOS selector is implemented differently between IPv4 and
IPv6. In IPv4 it is used to match on the three "Type of Services" bits
specified in RFC 791, while in IPv6 is it is used to match on the six
DSCP bits specified in RFC 2474.
Add a new FIB rule attribute to allow matching on DSCP. The attribute
will be used to implement a 'dscp' selector in ip-rule with a consistent
behavior between IPv4 and IPv6.
For now, set the type of the attribute to 'NLA_REJECT' so that user
space will not be able to configure it. This restriction will be lifted
once both IPv4 and IPv6 support the new attribute.

The 3s threshold rang a bell, as this is the delay after which ALDPS

During the introduction of struct bpf_net_context handling for
XDP-redirect, the netkit driver has been missed, which also requires it
because NETKIT_REDIRECT invokes skb_do_redirect() which is accessing the
per-CPU variables. Otherwise we see the following crash:
BUG: kernel NULL pointer dereference, address: 0000000000000038
bpf_redirect()
netkit_xmit()
dev_hard_start_xmit()
Set the bpf_net_context before invoking netkit_xmit() program within the
netkit driver.

In cases when synchronizing DMA operations is necessary,
xsk_buff_alloc_batch() returns a single buffer instead of the requested
count. This puts the pressure on drivers that use batch API as they have
to check for this corner case on their side and take care of allocations
by themselves, which feels counter productive. Let us improve the core
by looping over xp_alloc() @max times when slow path needs to be taken.
Another issue with current interface, as spotted and fixed by Dries, was
that when driver called xsk_buff_alloc_batch() with @max == 0, for slow
path case it still allocated and returned a single buffer, which should
not happen. By introducing the logic from first paragraph we kill two
birds with one stone and address this problem as well.

The only difference is #reset-cells is not allowed in some of these,
but that aligns with actual users in .dts files.

arch/arm64/boot/dts/renesas/r8a77951-salvator-xs.dtb: clock-generator@6a: 'idt,output-enable-active' is a required property
From schema: Documentation/devicetree/bindings/clock/idt,versaclock5.yaml
Versaclock 5 clock generators can have their configuration stored in
One-Time Programmable (OTP) memory. Hence there is no need to specify
DT properties for manual configuration if the OTP has been programmed
before. Likewise, the Linux driver does not touch the SD/OE bits if the
corresponding properties are not specified, cfr. commit d83e561d43
("clk: vc5: Add properties for configuring SD/OE behavior").
Reflect this in the bindings by making the "idt,shutdown" and
"idt,output-enable-active" properties not required, just like the
various "idt,*" properties in the per-output child nodes.
