In prevision to add new UAPI for hwtstamp we will be limited to the struct
ethtool_ts_info that is currently passed in fixed binary format through the
ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code
already started operating on an extensible kernel variant of that
structure, similar in concept to struct kernel_hwtstamp_config vs struct
hwtstamp_config.
Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here
we introduce the kernel-only structure in include/linux/ethtool.h.
The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

This driver currently doesn't support any control flags.
Use flow_rule_match_has_control_flags() to check for control flags,
such as can be set through `tc flower ... ip_flags frag`.
In case any control flags are masked, flow_rule_match_has_control_flags()
sets a NL extended error message, and we return -EOPNOTSUPP.
Only compile-tested.

Since qede_parse_flow_attr() now does error reporting
through extack, then give it a fake extack and extract the
error message afterwards if one was set.
The extracted error message is then passed on through
DP_NOTICE(), including messages that was earlier issued
with DP_INFO().
This fake extack approach is already used by
mlxsw_env_linecard_modules_power_mode_apply() in
drivers/net/ethernet/mellanox/mlxsw/core_env.c

In order to pass EEE link modes beyond bit 32 to userspace we have to
complement the 32 bit bitmaps in struct ethtool_eee with linkmode
bitmaps. Therefore, similar to ethtool_link_settings and
ethtool_link_ksettings, add a struct ethtool_keee. In a first step
it's an identical copy of ethtool_eee. This patch simply does a
s/ethtool_eee/ethtool_keee/g for all users.

The get/set_rxfh ethtool ops currently takes the rxfh (RSS) parameters
as direct function arguments. This will force us to change the API (and
all drivers' functions) every time some new parameters are added.
This is part 1/2 of the fix, as suggested in [1]:
- First simplify the code by always providing a pointer to all params
(indir, key and func); the fact that some of them may be NULL seems
like a weird historic thing or a premature optimization.
It will simplify the drivers if all pointers are always present.
- Then make the functions take a dev pointer, and a pointer to a
single struct wrapping all arguments. The set_* should also take
an extack.

While performing certain power-off sequences, PCI drivers are
called to suspend and resume their underlying devices through
PCI PM (power management) interface. However this NIC hardware
does not support PCI PM suspend/resume operations so system wide
suspend/resume leads to bad MFW (management firmware) state which
causes various follow-up errors in driver when communicating with
the device/firmware afterwards.
To fix this driver implements PCI PM suspend handler to indicate
unsupported operation to the PCI subsystem explicitly, thus avoiding
system to go into suspended/standby mode.
Without this fix device/firmware does not recover unless system
is power cycled.

make versioncheck reports the following:

./drivers/net/ethernet/qlogic/qede/qede_ethtool.c: 7 linux/version.h not needed.
So remove linux/version.h from both of these files. Also remove
linux/compiler.h while at it as it is also not being used.

Even after commit 908d4bb7c54c ("qede: fix interrupt coalescing
configuration"), some entries of the coal_entry array may theoretically
be used uninitialized:
1. qede_alloc_fp_array() allocates QEDE_MAX_RSS_CNT entries for
coal_entry. The initial allocation uses kcalloc, so everything is
initialized.
2. The user sets a small number of queues (ethtool -L).
coal_entry is reallocated for the actual small number of queues.
3. The user sets a bigger number of queues.
coal_entry is reallocated bigger. The added entries are not
necessarily initialized.
In practice, the reallocations will actually keep using the originally
allocated region of memory, but we should not rely on it.
The reallocation is unnecessary. coal_entry can always have
QEDE_MAX_RSS_CNT entries.

On default driver load device gets configured with unexpected
higher interrupt coalescing values instead of default expected
values as memory allocated from krealloc() is not supposed to
be zeroed out and may contain garbage values.
Fix this by allocating the memory of required size first with
kcalloc() and then use krealloc() to resize and preserve the
contents across down/up of the interface.

A summary of the flags being set for various drivers is given below.
Note that XDP_F_REDIRECT_TARGET and XDP_F_FRAG_TARGET are features
that can be turned off and on at runtime. This means that these flags
may be set and unset under RTNL lock protection by the driver. Hence,
READ_ONCE must be used by code loading the flag value.
Also, these flags are not used for synchronization against the availability
of XDP resources on a device. It is merely a hint, and hence the read
may race with the actual teardown of XDP resources on the device. This
may change in the future, e.g. operations taking a reference on the XDP
resources of the driver, and in turn inhibiting turning off this flag.
However, for now, it can only be used as a hint to check whether device
supports becoming a redirection target.
Turn 'hw-offload' feature flag on for:
- netronome (nfp)
- netdevsim.
Turn 'native' and 'zerocopy' features flags on for:
- intel (i40e, ice, ixgbe, igc)
- mellanox (mlx5).
- stmmac
- netronome (nfp)
Turn 'native' features flags on for:
- amazon (ena)
- broadcom (bnxt)
- freescale (dpaa, dpaa2, enetc)
- funeth
- intel (igb)
- marvell (mvneta, mvpp2, octeontx2)
- mellanox (mlx4)

- qlogic (qede)
- sfc
- socionext (netsec)
- ti (cpsw)
- tap
- tsnep
- veth

Turn 'basic' (tx, pass, aborted and drop) features flags on for:
- netronome (nfp)
- cavium (thunder)
- hyperv.

Make sure that xdp_do_flush() is always executed before
napi_complete_done(). This is important for two reasons. First, a
redirect to an XSKMAP assumes that a call to xdp_do_redirect() from
napi context X on CPU Y will be followed by a xdp_do_flush() from the
same napi context and CPU. This is not guaranteed if the
napi_complete_done() is executed before xdp_do_flush(), as it tells
the napi logic that it is fine to schedule napi context X on another
CPU. Details from a production system triggering this bug using the
veth driver can be found following the first link below.
The second reason is that the XDP_REDIRECT logic in itself relies on
being inside a single NAPI instance through to the xdp_do_flush() call
for RCU protection of all in-kernel data structures. Details can be
found in the second link below.

Convert all remaining drivers that still use .adjfreq to the newer .adjfine
implementation. These drivers are not straightforward, as they use
non-standard methods of programming their hardware. They are all converted
to use scaled_ppm_to_ppb to get the parts per billion value that their
logic depends on.

We tell driver developers to always pass NAPI_POLL_WEIGHT
as the weight to netif_napi_add(). This may be confusing
to newcomers, drop the weight argument, those who really
need to tweak the weight can use netif_napi_add_weight().

Most drivers use "skb_transport_offset(skb) + tcp_hdrlen(skb)"
to compute headers length for a TCP packet, but others
use more convoluted (but equivalent) ways.
Add skb_tcp_all_headers() and skb_inner_tcp_all_headers()
helpers to harmonize this a bit.

Calling synchronize_irq() right before free_irq() is quite useless. On one
hand the IRQ can easily fire again before free_irq() is entered, on the
other hand free_irq() itself calls synchronize_irq() internally (in a race
condition free way), before any state associated with the IRQ is freed.

qede_build_skb() assumes build_skb() always works and goes straight
to skb_reserve(). However, build_skb() can fail under memory pressure.
This results in a kernel panic because the skb to reserve is NULL.
Add a check in case build_skb() failed to allocate and return NULL.
The NULL return is handled correctly in callers to qede_build_skb().
