OcteonTx2's next gen platform the CN10KB has RPM_USX MAC which has a
different serdes when compared to RPM MAC. Though the underlying
HW is different, the CSR interface has been designed largely inline
with RPM MAC, with few exceptions though. So we are using the same
CGX driver for RPM_USX MAC as well and will have a different set of APIs
for RPM_USX where ever necessary.

The RPM and RPM_USX blocks support a different number of LMACS.
RPM_USX support 8 LMACS per MAC block whereas legacy RPM supports only 4
LMACS per MAC. with this RPM_USX support double the number of DMAC filters
and fifo size.

This patch adds initial support for CN10KB's RPM_USX  MAC i.e registering
the driver and defining MAC operations (mac_ops). Adds the logic to
configure internal loopback and pause frames and assign FIFO length to
LMACS.

Kernel reads lmac features like lmac type, autoneg, etc from shared
firmware data this structure only supports 4 lmacs per MAC, this patch
extends this structure to accommodate 8 lmacs.

Most of the code in CGX/RPM driver assumes that max lmacs per
given MAC as always, 4 and the number of MAC blocks also as 4.
With this assumption, the max number of interfaces supported is
hardcoded to 16. This creates a problem as next gen CN10KB silicon
MAC supports 8 lmacs per MAC block.

This patch solves the problem by using "max lmac per MAC block"
value from constant csrs and uses cgx_cnt_max value which is
populated based number of MAC blocks supported by silicon.

Make MTU configurable on KSZ87xx and KSZ88xx series of switches.

Before this patch, pre-configured behavior was different on different
switch series, due to opposite meaning of the same bit:
- KSZ87xx: Reg 4, Bit 1 - if 1, max frame size is 1532; if 0 - 1514
- KSZ88xx: Reg 4, Bit 1 - if 1, max frame size is 1514; if 0 - 1532

Since the code was telling "... SW_LEGAL_PACKET_DISABLE, true)", I
assume, the idea was to set max frame size to 1532.

With this patch, by setting MTU size 1500, both switch series will be
configured to the 1532 frame limit.

This patch was tested on KSZ8873.

We currently have some complicated code in sfp_probe() which gets the

completely separate lookup functions.

This could do with being in a separate function to make the code more

fwnode_find_reference() to lookup the I2C bus fwnode before then
decending into fwnode-type specific parsing.

A future cleanup would be to move the fwnode-type specific parsing into
the i2c layer, which is where it really should be.

Before it was not allowed to run ptp on ports that are part of a bridge
because in case of transparent clock the HW will still forward the frames
so there would be duplicate frames.
Now that there is VCAP support, it is possible to add entries in the VCAP
to trap frames to the CPU and the CPU will forward these frames.
The first part of the patch series, extends the VCAP support to be able to
modify and get the rule, while the last patch uses the VCAP to trap the ptp
frames.

Merge tag 'rxrpc-next-20221201-b' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

David Howells says:

====================
rxrpc: Increasing SACK size and moving away from softirq, parts 2 & 3

Here are the second and third parts of patches in the process of moving
rxrpc from doing a lot of its stuff in softirq context to doing it in an
I/O thread in process context and thereby making it easier to support a
larger SACK table.

The full description is in the description for the first part[1] which is
already in net-next.

The second part includes some cleanups, adds some testing and overhauls
some tracing:

 (1) Remove declaration of rxrpc_kernel_call_is_complete() as the
     definition is no longer present.

 (2) Remove the knet() and kproto() macros in favour of using tracepoints.

 (3) Remove handling of duplicate packets from recvmsg.  The input side
     isn't now going to insert overlapping/duplicate packets into the
     recvmsg queue.

 (4) Don't use the rxrpc_conn_parameters struct in the rxrpc_connection or
     rxrpc_bundle structs - rather put the members in directly.

 (5) Extract the abort code from a received abort packet right up front
     rather than doing it in multiple places later.

 (6) Use enums and symbol lists rather than __builtin_return_address() to
     indicate where a tracepoint was triggered for local, peer, conn, call
     and skbuff tracing.

 (7) Add a refcount tracepoint for the rxrpc_bundle struct.

 (8) Implement an in-kernel server for the AFS rxperf testing program to
     talk to (enabled by a Kconfig option).

This is tagged as rxrpc-next-20221201-a.

The third part introduces the I/O thread and switches various bits over to
running there:

 (1) Fix call timers and call and connection workqueues to not hold refs on
     the rxrpc_call and rxrpc_connection structs to thereby avoid messy
     cleanup when the last ref is put in softirq mode.

 (2) Split input.c so that the call packet processing bits are separate
     from the received packet distribution bits.  Call packet processing
     gets bumped over to the call event handler.

 (3) Create a per-local endpoint I/O thread.  Barring some tiny bits that
     still get done in softirq context, all packet reception, processing
     and transmission is done in this thread.  That will allow a load of
     locking to be removed.

 (4) Perform packet processing and error processing from the I/O thread.

 (5) Provide a mechanism to process call event notifications in the I/O
     thread rather than queuing a work item for that call.

 (6) Move data and ACK transmission into the I/O thread.  ACKs can then be
     transmitted at the point they're generated rather than getting
     delegated from softirq context to some process context somewhere.

 (7) Move call and local processor event handling into the I/O thread.

 (8) Move cwnd degradation to after packets have been transmitted so that
     they don't shorten the window too quickly.

A bunch of simplifications can then be done:

 (1) The input_lock is no longer necessary as exclusion is achieved by
     running the code in the I/O thread only.

 (2) Don't need to use sk->sk_receive_queue.lock to guard socket state
     changes as the socket mutex should suffice.

 (3) Don't take spinlocks in RCU callback functions as they get run in
     softirq context and thus need _bh annotations.

 (4) RCU is then no longer needed for the peer's error_targets list.

 (5) Simplify the skbuff handling in the receive path by dropping the ref
     in the basic I/O thread loop and getting an extra ref as and when we
     need to queue the packet for recvmsg or another context.

 (6) Get the peer address earlier in the input process and pass it to the
     users so that we only do it once.

This is tagged as rxrpc-next-20221201-b.

Changes:
========
ver #2)
 - Added a patch to change four assertions into warnings in rxrpc_read()
   and fixed a checker warning from a __user annotation that should have
   been removed..
 - Change a min() to min_t() in rxperf as PAGE_SIZE doesn't seem to match
   type size_t on i386.
 - Three error handling issues in rxrpc_new_incoming_call():
   - If not DATA or not seq #1, should drop the packet, not abort.
   - Fix a goto that went to the wrong place, dropping a non-held lock.
   - Fix an rcu_read_lock that should've been an unlock.

Meanwhile we have sysfs attributes for controlling kind of
"software interrupt coalescing" on the GRO level. However most distros
and users don't know about it. So lets set a conservative default for
both involved parameters. Users can still override the defaults via
sysfs. Don't enable these settings on the fast ethernet chip versions,
they are slow enough.

Even with these conservative setting interrupt load on my 1Gbps test

Nathan noticed that when HWSPINLOCK is disabled there's a Kconfig warning:

  WARNING: unmet direct dependencies detected for QCOM_SMEM
    Depends on [n]: (ARCH_QCOM [=y] || COMPILE_TEST [=n]) && HWSPINLOCK [=n]
    Selected by [m]:
    - ATH10K_SNOC [=m] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_ATH [=y] && ATH10K [=m] && (ARCH_QCOM [=y] || COMPILE_TEST [=n])

The problem here is that QCOM_SMEM depends on HWSPINLOCK so we cannot select
QCOM_SMEM and instead we neeed to use 'depends on'.

Refill RX queue in batches of descriptors to improve performance. Refill
is allowed to fail as long as a minimum number of descriptors is active.
Thus, a limited number of failed RX buffer allocations is now allowed
for normal operation. Previously every failed allocation resulted in a
dropped frame.

If the minimum number of active descriptors is reached, then RX buffers
are still reused and frames are dropped. This ensures that the RX queue
never runs empty and always continues to operate.

Prework for future XDP support.

Without interrupt throttling, iperf server mode generates a CPU load of
100% (A53 1.2GHz). Also the throughput suffers with less than 900Mbit/s
on a 1Gbit/s link. The reason is a high interrupt load with interrupts
every ~20us.

Reduce interrupt load by throttling of interrupts. Interrupt delay
default is 64us. For iperf server mode the CPU load is significantly
reduced to ~20% and the throughput reaches the maximum of 941MBit/s.
Interrupts are generated every ~140us.

RX and TX coalesce can be configured with ethtool. RX coalesce has
priority over TX coalesce if the same interrupt is used.

Allow user space to read number of TX and RX queue. This is useful for
device dependent qdisc configurations like TAPRIO with hardware offload.
Also ethtool::get_per_queue_coalesce / set_per_queue_coalesce requires
that interface.
