net: dsa: add support for RTL8365MB-VC

This series adds support for Realtek's RTL8365MB-VC, a 4+1 port
10/100/1000M Ethernet switch. The driver - rtl8365mb - was developed by
Michael Ramussen and myself.

This version of the driver is relatively slim, implementing only the
standalone port functionality and no offload capabilities. It is based
on a previous RFC series [1] from August, and the main difference is the
removal of some spurious VLAN operations. Otherwise I have simply
addressed most of the feedback. Please see the respective patches for
more detail.

In parallel I am working on offloading the bridge layer capabilities,
but I would like to get the basic stuff upstreamed as soon as possible.

v3 -> v4:
  - get irq before setting virq parents (fixes kernel test robot
    warning)
  - remove pad-to-72-bytes logic in tagger xmit (fixes DENG Qingfang's
    suggestion); no longer needed as we set CPU minimum RX size to 64
    bytes
  - use mutex to protect MIB counter access instead of a spinlock (fixes
    Jakub's feedback on v3 statistics refactoring)

v2 -> v3:
  - move IRQ setup earlier in probe per Florian's suggestion
  - fix compilation error on some archs due to FIELD_PREP use in v1
  - follow Jakub's suggestion and use the standard ethtool stats API;
    NOTE: new patch in the series for relevant DSA plumbing
  - following the stats change, it became apparent that the rtl8366
    helper library is no longer that helpful; scrap it and implement
    the ethtool ops specifically for this chip

v1 -> v2:
  - drop DSA port type checks during MAC configuration
  - use OF properties to configure RGMII TX/RX delay
  - don't set default fwd_offload_mark if packet is trapped to CPU
  - remove port mapping macros
  - update device tree bindings documentation with an example
  - cosmetic changes to the tagging driver using FIELD_* macros

This patch adds a realtek-smi subdriver for the RTL8365MB-VC 4+1 port
10/100/1000M switch controller. The driver has been developed based on a
GPL-licensed OS-agnostic Realtek vendor driver known as rtl8367c found
in the OpenWrt source tree.

Despite the name, the RTL8365MB-VC has an entirely different register
layout to the already-supported RTL8366RB ASIC. Notwithstanding this,
the structure of the rtl8365mb subdriver is loosely based on the rtl8366rb
subdriver. Like the 'rb, it establishes its own irqchip to handle
cascaded PHY link status interrupts.

The RTL8365MB-VC switch is capable of offloading a large number of
features from the software, but this patch introduces only the most
basic DSA driver functionality. The ports always function as standalone
ports, with bridging handled in software.

One more thing. Realtek's nomenclature for switches makes it hard to
know exactly what other ASICs might be supported by this driver. The
vendor driver goes by the name rtl8367c, but as far as I can tell, no
chip actually exists under this name. As such, the subdriver is named
rtl8365mb to emphasize the potentially limited support. But it is clear
from the vendor sources that a number of other more advanced switches
share a similar register layout, and further support should not be too
hard to add given access to the relevant hardware. With this in mind,
the subdriver has been written with as few assumptions about the
particular chip as is reasonable. But the RTL8365MB-VC is the only
hardware I have available, so some further work is surely needed.

This commit implements a basic version of the 8 byte tag protocol used
in the Realtek RTL8365MB-VC unmanaged switch, which carries with it a
protocol version of 0x04.

The implementation itself only handles the parsing of the EtherType
value and Realtek protocol version, together with the source or
destination port fields. The rest is left unimplemented for now.

The tag format is described in a confidential document provided to my
company by Realtek Semiconductor Corp. Permission has been granted by
the vendor to publish this driver based on that material, together with
an extract from the document describing the tag format and its fields.
It is hoped that this will help future implementors who do not have
access to the material but who wish to extend the functionality of
drivers for chips which use this protocol.

In addition, two possible values of the REASON field are specified,
based on experiments on my end. Realtek does not specify what value this
field can take.

Try to simplify the gnet_stats and remove qdisc->running sequence counter.

The first few patches is a follow up to
    https://lore.kernel.org/all/20211007175000.2334713-1-bigeasy@linutronix.de/

The remaining patches (#5+) remove the seqcount_t (Qdisc::running) from
the Qdisc. The statistics (Qdisc::bstats and Qdisc::cpu_bstats) use
u64_stats_t and the "running state" is now represented by a bit in
Qdisc::state.

By removing the seqcount_t from Qdisc and decoupling the bstats
statistics from the seqcount_t it is possible to query the statistics
even if the Qdisc is running instead of waiting until it is idle again.

The try-lock like usage of the seqcount_t in qdisc_run_begin() is
problematic on PREEMPT_RT. Inside the qdisc_run_begin/end() qdisc->running
sequence counter write sections, at sch_direct_xmit(), the seqcount write
serialization lock is released then re-acquired. This is fine for !RT, because
the writer is in a BH disabled region and there is a no in-IRQ reader. For RT
though, BH sections are preemptible. The earlier introduced seqcount_LOCKNAME_t
mechanism, which for RT the reader acquires then relesaes the write
serailization lock to avoid infinite spinning if it preempts a seqcount write
section, cannot work: the qdisc->running write serialization lock is already
intermittingly released inside the seqcount write section.

The Qdisc::running sequence counter has two uses:

  1. Reliably reading qdisc's tc statistics while the qdisc is running
     (a seqcount read/retry loop at gnet_stats_add_basic()).

  2. As a flag, indicating whether the qdisc in question is running
     (without any retry loops).

For the first usage, the Qdisc::running sequence counter write section,
qdisc_run_begin() => qdisc_run_end(), covers a much wider area than what
is actually needed: the raw qdisc's bstats update. A u64_stats sync
point was thus introduced (in previous commits) inside the bstats
structure itself. A local u64_stats write section is then started and
stopped for the bstats updates.

Use that u64_stats sync point mechanism for the bstats read/retry loop
at gnet_stats_add_basic().

For the second qdisc->running usage, a __QDISC_STATE_RUNNING bit flag,
accessed with atomic bitops, is sufficient. Using a bit flag instead of
a sequence counter at qdisc_run_begin/end() and qdisc_is_running() leads
to the SMP barriers implicitly added through raw_read_seqcount() and
write_seqcount_begin/end() getting removed. All call sites have been
surveyed though, and no required ordering was identified.

Now that the qdisc->running sequence counter is no longer used, remove
it.

Note, using u64_stats implies no sequence counter protection for 64-bit
architectures. This can lead to the qdisc tc statistics "packets" vs.
"bytes" values getting out of sync on rare occasions. The individual
values will still be valid.

The only factor differentiating per-CPU bstats data type (struct

gnet_stats_basic_packed) was a u64_stats sync point inside the former.
The two data types are now equivalent: earlier commits added a u64_stats

Combine both data types into "struct gnet_stats_basic_sync". This
eliminates redundancy and simplifies the bstats read/write APIs.

The not-per-CPU variant of qdisc tc (traffic control) statistics,
Qdisc::gnet_stats_basic_packed bstats, is protected with Qdisc::running
sequence counter.

This sequence counter is used for reliably protecting bstats reads from
parallel writes. Meanwhile, the seqcount's write section covers a much
wider area than bstats update: qdisc_run_begin() => qdisc_run_end().

That read/write section asymmetry can lead to needless retries of the
read section. To prepare for removing the Qdisc::running sequence
counter altogether, introduce a u64_stats sync point inside bstats
instead.

Modify _bstats_update() to start/end the bstats u64_stats write
section.

For bisectability, and finer commits granularity, the bstats read
section is still protected with a Qdisc::running read/retry loop and
qdisc_run_begin/end() still starts/ends that seqcount write section.
Once all call sites are modified to use _bstats_update(), the
Qdisc::running seqcount will be removed and bstats read/retry loop will
be modified to utilize the internal u64_stats sync point.

Note, using u64_stats implies no sequence counter protection for 64-bit
architectures. This can lead to the statistics "packets" vs. "bytes"
values getting out of sync on rare occasions. The individual values will
still be valid.
