net: dsa: sja1105: don't use burst SPI reads for port statistics
The current internal sja1105 driver API is optimized for retrieving many
statistics counters at once. But the switch does not do atomic snapshotting
for them anyway.
In case we start reporting the hardware port counters through
ndo_get_stats64 as well, not just ethtool, it would be good to be able
to read individual port counters and not all of them.
Additionally, since Arnd Bergmann's commit
ae1804de93f6 ("dsa: sja1105:
dynamically allocate stats structure"), sja1105_get_ethtool_stats
allocates memory dynamically, since struct sja1105_port_status was
deemed to consume too much stack memory. That is not ideal.
The large structure is only needed because of the burst read.
If we read statistics one by one, we can consume less memory, and
we can avoid dynamic allocation.
Additionally, latency-sensitive interfaces such as PTP operations (for
phc2sys) might suffer if the SPI mutex is being held for too long, which
happens in the case of SPI burst reads. By reading counters one by one,
we give a chance for higher priority processes to preempt and take the
SPI bus mutex for accessing the PTP clock.

net: dsa: sja1105: adapt to a SPI controller with a limited max transfer size
The static config of the sja1105 switch is a long stream of bytes which
is programmed to the hardware in chunks (portions with the chip select
continuously asserted) of max 256 bytes each. Each chunk is a
spi_message composed of 2 spi_transfers: the buffer with the data and a
preceding buffer with the SPI access header.
Only that certain SPI controllers, such as the spi-sc18is602 I2C-to-SPI
bridge, cannot keep the chip select asserted for that long.
The spi_max_transfer_size() and spi_max_message_size() functions are how
the controller can impose its hardware limitations upon the SPI
peripheral driver.
For the sja1105 driver to work with these controllers, both buffers must
be smaller than the transfer limit, and their sum must be smaller than
the message limit.
Regression-tested on a switch connected to a controller with no
limitations (spi-fsl-dspi) as well as with one with caps for both
max_transfer_size and max_message_size (spi-sc18is602).

net: dsa: sja1105: send multiple spi_messages instead of using cs_change
The sja1105 driver has been described by Mark Brown as "not using the
[ SPI ] API at all idiomatically" due to the use of cs_change:
https://patchwork.kernel.org/project/netdevbpf/patch/
20210520135031.
2969183-1-olteanv@gmail.com/
According to include/linux/spi/spi.h, the chip select is supposed to be
asserted for the entire length of a SPI message, as long as cs_change is
false for all member transfers. The cs_change flag changes the following:
(i) When a non-final SPI transfer has cs_change = true, the chip select
should temporarily deassert and then reassert starting with the next
transfer.
(ii) When a final SPI transfer has cs_change = true, the chip select
should remain asserted until the following SPI message.
The sja1105 driver only uses cs_change for its first property, to form a
single SPI message whose layout can be seen below:
this is an entire, single spi_message
_______________________________________________________________________________________________
/ \
+-------------+---------------+-------------+---------------+ ... +-------------+---------------+
| hdr_xfer[0] | chunk_xfer[0] | hdr_xfer[1] | chunk_xfer[1] | | hdr_xfer[n] | chunk_xfer[n] |
+-------------+---------------+-------------+---------------+ ... +-------------+---------------+
cs_change false true false true false false
____________________________ _____________________________ _____________________________
CS line __/ \/ \ ... / \__
The fact of the matter is that spi_max_message_size() has an ambiguous
meaning if any non-final transfer has cs_change = true.
If the SPI master has a limitation in that it cannot keep the chip
select asserted for more than, say, 200 bytes (like the spi-sc18is602),
the normal thing for it to do is to implement .max_transfer_size and
.max_message_size, and limit both to 200: in the "worst case" where
cs_change is always false, then the controller can, indeed, not send
messages larger than 200 bytes.
But the fact that the SPI controller's max_message_size does not
necessarily mean that we cannot send messages larger than that.
Notably, if the SPI master special-cases the transfers with cs_change
and treats every chip select toggling as an entirely new transaction,
then a SPI message can easily exceed that limit. So there is a
temptation to ignore the controller's reported max_message_size when
using cs_change = true in non-final transfers.
But that can lead to false conclusions. As Mark points out, the SPI
controller might have a different kind of limitation with the max
message size, that has nothing at all to do with how long it can keep
the chip select asserted.
For example, that might be the case if the device is able to offload the
chip select changes to the hardware as part of the data stream, and it
packs the entire stream of commands+data (corresponding to a SPI
message) into a single DMA transfer that is itself limited in size.
So the only thing we can do is avoid ambiguity by not using cs_change at
all. Instead of sending a single spi_message, we now send multiple SPI
messages as follows:
spi_message 0 spi_message 1 spi_message n
____________________________ ___________________________ _____________________________
/ \ / \ / \
+-------------+---------------+-------------+---------------+ ... +-------------+---------------+
| hdr_xfer[0] | chunk_xfer[0] | hdr_xfer[1] | chunk_xfer[1] | | hdr_xfer[n] | chunk_xfer[n] |
+-------------+---------------+-------------+---------------+ ... +-------------+---------------+
cs_change false true false true false false
____________________________ _____________________________ _____________________________
CS line __/ \/ \ ... / \__
which is clearer because the max_message_size limit is now easier to
enforce. What is transmitted on the wire stays, of course, the same.
Additionally, because we send no more than 2 transfers at a time, we now
avoid dynamic memory allocation too, which might be seen as an
improvement by some.

====================
1GbE Intel Wired LAN Driver Updates 2021-05-20
This series contains updates to igc driver only.
Andre Guedes says:
This series adds AF_XDP zero-copy feature to igc driver.
The initial patches do some code refactoring, preparing the code base to
land the AF_XDP zero-copy feature, avoiding code duplications. The last
patches of the series are the ones implementing the feature.
The last patch which indeed implements AF_XDP zero-copy support was
originally way too lengthy so, for the sake of code review, I broke it
up into two patches: one adding support for the RX functionality and the
other one adding TX support.
---
v2:
Patch 8/9 - "igc: Enable RX via AF_XDP zero-copy"
* In XDP_PASS flow, copy metadata too into the skb.
* When HW timestamp is added by the NIC, after copying it into
a local variable, update xdp_buff->data_meta so that
metadata length when XDP program is called 0.
* In igc_xdp_enable_pool(), call xsk_pool_dma_unmap() on
failure.
Known issues:
When an XDP application is running in Tx-Only mode with Zero-Copy
enabled, it is not expected to add the frames to the fill-queue. I have
noticed the following two issues in this scenario:
- If XDP_USE_NEED_WAKEUP flag is not set by application, igc_poll()
will go into infinite loop because the buffer allocation resulting
in igc_clean_rx_irq_zc() indicating that all work is not done and NAPI
should keep polling. This does not occur if XDP_USE_NEED_WAKEUP
flag is set.
- Since there are no buffers allocated by userspace for the fill
queue, there is no memory allocated for the NIC to copy the data
to. If the packet received is destined to the hardware queue where
XDP application is running, no packets are received even on other
queues.
Both these issues can be mitigated by adding a few frames to the
fill queue. The second issue can also be mitigated by making sure no
packets are being received on the hardware queue where Rx is running.

igc: Enable TX via AF_XDP zero-copy
Add support for transmitting packets via AF_XDP zero-copy mechanism.
The packet transmission itself is implemented by igc_xdp_xmit_zc() which
is called from igc_clean_tx_irq() when the ring has AF_XDP zero-copy
enabled. Likewise i40e and ice drivers, the transmission budget used is
the number of descriptors available on the ring.
A new tx buffer type is introduced to 'enum igc_tx_buffer_type' to
indicate the tx buffer uses memory from xsk pool so it can be properly
cleaned after transmission or when the ring is cleaned.
The I225 controller has only 4 Tx hardware queues so the main difference
between igc and other Intel drivers that support AF_XDP zero-copy is
that there is no tx ring dedicated exclusively to XDP. Instead, tx
rings are shared between the network stack and XDP, and netdev queue
lock is used to ensure mutual exclusion. This is the same approach
implemented to support XDP_TX and XDP_REDIRECT actions.

igc: Enable RX via AF_XDP zero-copy
Add support for receiving packets via AF_XDP zero-copy mechanism.
Add a new flag to 'enum igc_ring_flags_t' to indicate the ring has
AF_XDP zero-copy enabled so proper ring setup is carried out during ring
configuration in igc_configure_rx_ring().
RX buffers can now be allocated via the shared pages mechanism (default
behavior of the driver) or via xsk pool (when AF_XDP zero-copy is
enabled) so a union is added to the 'struct igc_rx_buffer' to cover both
cases.
When AF_XDP zero-copy is enabled, rx buffers are allocated from the xsk
pool using the new helper igc_alloc_rx_buffers_zc() which is the
counterpart of igc_alloc_rx_buffers().
Likewise other Intel drivers that support AF_XDP zero-copy, in igc we
have a dedicated path for cleaning up rx irqs when zero-copy is enabled.
This avoids adding too many checks within igc_clean_rx_irq(), resulting
in a more readable and efficient code since this function is called from
the hot-path of the driver.

mlxsw: spectrum_router: Add support for inner layer 3 multipath hash policy
When this policy is set, the kernel uses the inner layer 3 fields for
multipath hash computation and falls back to the outer fields if no
encapsulation was encountered. This behavior is most likely influenced
by the behavior of the flow dissector, which is used for the packet
dissection.
The Spectrum ASIC, however, cannot fallback to outer fields if inner
fields are not available. This should not result in a discrepancy from
the software data path because if several flows have matching inner
fields, they will tend to have matching outer fields as well.
Therefore, implement this policy by enabling both outer and inner layer
3 fields for the multipath hash computation.
