749da8ca97 clocksource/drivers/hyper-v: Make sched clock return nanoseconds correctly
The sched clock read functions return the HV clock (100ns granularity)
without converting it to nanoseconds.

Add the missing conversion.

84acc85a62 iwlwifi: mvm: remove newline from rs_pretty_print_rate()
Some of the places using this want the newline, but not all,
so remove the newline from it and generate it in the debugfs
files where it's desired.

The effect of this is not printing double newlines in debug
log messages.

a72abfca95 iwlwifi: add trans_cfg for devices with long latency
A couple of SoCs, which can be recognized by PCI device IDs 0xA0F0 and
0x43F0, need a longer wait for the xtal to stabilize.  To handle this,
add a new trans_cfg structure for Qu devices with a larger
xtal_latency value and apply them to the devices recognized by these
IDs.  Also add a flag that allows us to inform the FW that the low
latency xtal should be used.

095650c054 iwlwifi: add support for version 2 of SOC_CONFIGURATION_CMD
This new command is mostly backwards compatible, with the exception
that the device_type element was changed into a bitmask.  The device
type bit remains the same (because we only had 0 and 1 anyway), but
when using v1 we can't set any other bits, because that would change
the integer.

Other than that, the struct remains the same and the driver can set
the device_type bit in both cases, but it can only set the low_latency
bit if VER_2 is used.

7897dfa2bc iwlwifi: move integrated, extra_phy and soc_latency to trans_cfg
These values are selected based on the PCI device ID, so the decision
to use them can be made early.  By moving them to the trans_cfg, we
avoid duplicating the large cfg structs for small pieces of
data (sometimes a single boolean).  This will also allow us to make
more decisions based on, for instance, the SoC type in used.

The trans_cfg concept changes a bit, because previously it was used
only to boot the device before reading further characteristics and now
it also contains more data that is associated with the device ID.

So far we set phydev->suspended to true in phy_suspend() even if the
PHY driver doesn't implement the suspend callback. This applies
accordingly for the resume path. The current behavior doesn't cause
any issue I'd be aware of, but it's not logical and misleading,
especially considering the description of the flag:
"suspended: Set to true if this phy has been suspended successfully"

8262e6f9b1 net: ks8851-ml: Fix IO operations, again
This patch reverts 5829210483 ("net: ks8851-ml: Fix 16-bit IO operation")
and edacb098ea ("net: ks8851-ml: Fix 16-bit data access"), because it
turns out these were only necessary due to buggy hardware. This patch adds
a check for such a buggy hardware to prevent any such mistakes again.

While working further on the KS8851 driver, it came to light that the
KS8851-16MLL is capable of switching bus endianness by a hardware strap,
EESK pin. If this strap is incorrect, the IO accesses require such endian
swapping as is being reverted by this patch. Such swapping also impacts
the performance significantly.

Hence, in addition to removing it, detect that the hardware is broken,
report to user, and fail to bind with such hardware.

Igor Russkikh says:

====================
net: atlantic: MACSec support for AQC devices

This patchset introduces MACSec HW offloading support in
Marvell(Aquantia) AQC atlantic driver.

This implementation is a joint effort of Marvell developers on top of
the work started by Antoine Tenart.

v2:
 * clean up the generated code (removed useless bit operations);
 * use WARN_ONCE to avoid log spam;
 * use put_unaligned_be64;
 * removed trailing \0 and length limit for format strings;

v1: https://patchwork.ozlabs.org/cover/1259998/

RFC v2: https://patchwork.ozlabs.org/cover/1252204/

RFC v1: https://patchwork.ozlabs.org/cover/1238082/

Several patches introduce backward-incompatible changes and are
subject for discussion/drop:

1) patch 0007:
  multicast/broadcast when offloading is needed to handle ARP requests,
  because they have broadcast destination address;
  With this patch we also match and encrypt/decrypt packets between macsec
  hw and realdev based on device's mac address.
  This can potentially be used to support multiple macsec offloaded
  interfaces on top of one realdev.
  However in some environments this could lead to problems, e.g. the
  'bridge over macsec' configuration will expect the packets with unknown
  src MAC should come through macsec.
  The patch is questionable, we've used it because our current hw setup
  and requirements both assume that the decryption is done based on mac
  address match only.
  This could be changed by encrypting/decripting all the traffic (except
  control).

2) patch 0009:
  real_dev features are now propagated to macsec device (when HW
  offloading is enabled), otherwise feature set might lead to HW
  reconfiguration during MACSec configuration.
  Also, HW offloaded macsec should be able to keep LRO LSO features,
  since they are transparent for macsec engine (at least in our hardware).

b8f8a0b7b5 net: atlantic: MACSec ingress offload HW bindings
This patch adds the Atlantic HW-specific bindings for MACSec ingress, e.g.
register addresses / structs, helper function, etc, which will be used by

62c1c2e606 net: atlantic: MACSec offload skeleton
This patch adds basic functionality for MACSec offloading for Atlantic
NICs.

MACSec offloading functionality is enabled if network card has
appropriate FW that has MACSec offloading enabled in config.

Actual functionality (ingress, egress, etc) will be added in follow-up
patches.

c850240b6c net: macsec: report real_dev features when HW offloading is enabled
This patch makes real_dev_feature propagation by MACSec offloaded device.

Issue description:
real_dev features are disabled upon macsec creation.

Root cause:
Features limitation (specific to SW MACSec limitation) is being applied
to HW offloaded case as well.
This causes 'set_features' request on the real_dev with reduced feature
set due to chain propagation.

Proposed solution:
Report real_dev features when HW offloading is enabled.
NB! MACSec offloaded device does not propagate VLAN offload features at
the moment. This can potentially be added later on as a separate patch.

Note: this patch requires HW offloading to be enabled by default in order
to function properly.

f428011b90 net: macsec: support multicast/broadcast when offloading
The idea is simple. If the frame is an exact match for the controlled port
(based on DA comparison), then we simply divert this skb to matching port.

Multicast/broadcast messages are delivered to all ports.
