This patch implements the TDR test procedure as described in
"Application Note DP83TD510E Cable Diagnostics Toolkit revC", section 3.2.
The procedure was tested with "draka 08 signalkabel 2x0.8mm". The reported
cable length was 5 meters more for each 20 meters of actual cable length.
For instance, a 20-meter cable showed as 25 meters, and a 40-meter cable
showed as 50 meters. Since other parts of the diagnostics provided by this
PHY (e.g., Active Link Cable Diagnostics) require accurate cable
characterization to provide proper results, this tuning can be implemented
in a separate patch/interface.

ARFS depends on NTUPLE filters, but the inverse is not true.
Drivers which don't support ARFS commonly still support NTUPLE
filtering. mlx5 has a Kconfig option to disable ARFS (MLX5_EN_ARFS)
and does not advertise NTUPLE filters as a feature at all when ARFS
is compiled out. That's not correct, ntuple filters indeed still work
just fine (as long as MLX5_EN_RXNFC is enabled).
This is needed to make the RSS test not skip all RSS context
related testing.

When setting max_io_eqs for an SF function also set the sf_eq_usage_cap.
This is to indicate to the SF driver from the PF that the user has set
the max io eqs via devlink. So the SF driver can later query the proper
max eq value from the new cap.

Change the data type of the variable freq in mvpp2_rx_time_coal_set()
and mvpp2_tx_time_coal_set() to u32 because port->priv->tclk also has
the data type u32.
Change the data type of the function parameter clk_hz in
mvpp2_usec_to_cycles() and mvpp2_cycles_to_usec() to u32 accordingly
and remove the following Coccinelle/coccicheck warning reported by
do_div.cocci:

git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue
Tony Nguyen says:
====================
idpf: XDP chapter I: convert Rx to libeth
Alexander Lobakin says:
XDP for idpf is currently 5 chapters:
* convert Rx to libeth (this);
* convert Tx and stats to libeth;
* generic XDP and XSk code changes, libeth_xdp;
* actual XDP for idpf via libeth_xdp;
* XSk for idpf (^).
Part I does the following:
* splits &idpf_queue into 4 (RQ, SQ, FQ, CQ) and puts them on a diet;
* ensures optimal cacheline placement, strictly asserts CL sizes;
* moves currently unused/dead singleq mode out of line;
* reuses libeth's Rx ptype definitions and helpers;
* uses libeth's Rx buffer management for both header and payload;
* eliminates memcpy()s and coherent DMA uses on hotpath, uses
napi_build_skb() instead of in-place short skb allocation.
Most idpf patches, except for the queue split, removes more lines
than adds.
Expect far better memory utilization and +5-8% on Rx depending on
the case (+17% on skb XDP_DROP :>).
* '200GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
idpf: use libeth Rx buffer management for payload buffer
idpf: convert header split mode to libeth + napi_build_skb()
libeth: support different types of buffers for Rx
idpf: remove legacy Page Pool Ethtool stats
idpf: reuse libeth's definitions of parsed ptype structures
idpf: compile singleq code only under default-n CONFIG_IDPF_SINGLEQ
idpf: merge singleq and splitq &net_device_ops
idpf: strictly assert cachelines of queue and queue vector structures
idpf: avoid bloating &idpf_q_vector with big %NR_CPUS
idpf: split &idpf_queue into 4 strictly-typed queue structures
idpf: stop using macros for accessing queue descriptors
libeth: add cacheline / struct layout assertion helpers
page_pool: use __cacheline_group_{begin, end}_aligned()
cache: add __cacheline_group_{begin, end}_aligned() (+ couple more)

Instead of allocating a separate indir table in the vnic use
the one already present in the RSS context allocated by the core.
This saves some LoC and also we won't have to worry about syncing
the local version back to the core, once core learns how to dump
contexts.

Ethtool core stores indirection table with u32 entries, "just to be safe".
Switch the type in the driver, so that it's easier to swap local tables
for the core ones. Memory allocations already use sizeof(*entry), switch
the memset()s as well.

bnxt allocates tables of max size, and changes the used size
based on number of active rings. The unused entries get padded
out with zeros. bnxt_modify_rss() seems to always pad out
the table of the main / default RSS context, instead of
the table of the modified context.
I haven't observed any behavior change due to this patch,
so I don't think it's a fix. Not entirely sure what role
the padding plays, 0 is a valid queue ID.

Core can allocate space for per-context driver-private data,
use it for struct bnxt_rss_ctx. Inline bnxt_alloc_rss_ctx()
at this point, most of the init (as in the actions bnxt_del_one_rss_ctx()
will undo) is open coded in bnxt_create_rxfh_context(), anyway.

Use the new ethtool ops for RSS context management. The conversion
is pretty straightforward cut / paste of the right chunks of the
combined handler. Main change is that we let the core pick the IDs
(bitmap will be removed separately for ease of review), so we need
to tell the core when we lose a context.
Since the new API passes rxfh as const, change bnxt_modify_rss()
to also take const.

Contexts get deleted from FW when the device is down, but they
are kept in SW and re-added back on open. bnxt_set_rxfh_context()
apparently does not want to deal with complexity of dealing with
both the device down and device up cases. This is perhaps acceptable
for creating new contexts, but not being able to delete contexts
makes core-driven cleanups messy. Specifically with the new RSS
API core will try to delete contexts automatically after bringing
the device down.
Support the delete-while-down case. Skip the FW logic and delete
just the driver state.

If we encounter an error on i2c packet transmit, we won't have a valid
flow anymore; since we didn't transmit a valid packet sequence, we'll
have to wait for the key to timeout instead of dropping it on the reply.
This causes the i2c lock to be held for longer than necessary.
Instead, invalidate the flow on TX error, and release the i2c lock
immediately.

When disabling a netconsole target, enabled_store() is called with
enabled=false. Currently, this results in updating the nt->enabled
field twice:
1. Inside the if/else block, with the target_list_lock spinlock held
2. Later, without the target_list_lock
This patch eliminates the redundancy by setting the field only once,
improving efficiency and reducing potential race conditions.

Remove wrong EIO to EGAIN conversion and pass all errors as is.
After commit 230f3d53a547 ("i40e: remove i40e_status"), which should only
replace F/W specific error codes with Linux kernel generic, all EIO errors
suddenly started to be converted into EAGAIN which leads nvmupdate to retry
until it timeouts and sometimes fails after more than 20 minutes in the
middle of NVM update, so NVM becomes corrupted.
The bug affects users only at the time when they try to update NVM, and
only F/W versions that generate errors while nvmupdate. For example, X710DA2
with 0x8000ECB7 F/W is affected, but there are probably more...
Command for reproduction is just NVM update:
./nvmupdate64
In the log instead of:
i40e_nvmupd_exec_aq err I40E_ERR_ADMIN_QUEUE_ERROR aq_err I40E_AQ_RC_ENOMEM)
appears:
i40e_nvmupd_exec_aq err -EIO aq_err I40E_AQ_RC_ENOMEM
i40e: eeprom check failed (-5), Tx/Rx traffic disabled
The problematic code did silently convert EIO into EAGAIN which forced
nvmupdate to ignore EAGAIN error and retry the same operation until timeout.
That's why NVM update takes 20+ minutes to finish with the fail in the end.

The other is a series of fixes from David Lechner for his recent

The amount of TX space in the hardware buffer is tracked in the tx_space
variable. The initial value is currently only set during driver probing.
After closing the interface and reopening it the tx_space variable has
the last value it had before close. If it is smaller than the size of
the first send packet after reopeing the interface the queue will be
stopped. The queue is woken up after receiving a TX interrupt but this
will never happen since we did not send anything.
This commit moves the initialization of the tx_space variable to the
ks8851_net_open function right before starting the TX queue. Also query
the value from the hardware instead of using a hard coded value.
Only the SPI chip variant is affected by this issue because only this
driver variant actually depends on the tx_space variable in the xmit
function.
