ethtool: drop get_settings and set_settings ops

As Andrew Lunn pointed out in recent discussion, there is only one in tree
driver left which still defines deprecated callbacks get_settings() and
set_settings() in ethtool_ops. First patch converts this driver to
get_link_ksettings() and set_link_ksettings(). Second patch then removes
the deprecated callbacks from struct ethtool_ops and ethtool code which
falls back to them.

This doesn't break old versions of ethtool or any other userspace code
using ETHTOOL_{G,S}SET. We still implement both (old) ETHTOOL_{G,S}SET and
(new) ETHTOOL_{G,S}LINKSETTINGS ioctl commands but after this series both
will be implemented only using {g,s}et_link_ksettings(). The only affected
code would be out of tree NIC drivers which have not been converted yet.
====================

Since [gs]et_settings ethtool_ops callbacks have been deprecated in
February 2016, all in tree NIC drivers have been converted to provide
[gs]et_link_ksettings() and out of tree drivers have had enough time to do
the same.

Drop get_settings() and set_settings() and implement both ETHTOOL_[GS]SET
and ETHTOOL_[GS]LINKSETTINGS only using [gs]et_link_ksettings().

Note: this is only build tested. I don't have the hardware at hand; as it's

nfp: add NFP5000 support

This series broadly speaking adds support for NFP5000 and
related products.

First we add support for loading FW from flash.  We need to allow
for the management processor to provide extended log messages when
FW is loaded.  This is needed when FW selection policy is to compare
the FW on the disk and in the flash, and load the newer.  User should
be told what FW was selected.

We use this opportunity to add extended errors for normal FW loading
as well.

Next we add support for requesting HW information from the management
processor.  Up until now the driver read the HWinfo as it appears in
card memory, but there can be cases when management processor has
additional information or generates the entries dynamically so
occasionally we will have to consult it.  We use this to look up MAC
addresses for PCIe netdevs.

Next the actual patch with NFP5000 support and a small dose of
refactoring of PCIe init.

The remaining patches add support for reading RTsymbol types we
didn't need before.  Ones explicitly placed in external memory unit's
cache and absolute ones.

This part begins with a patch moving the logic which figures out
the correct bit offsets to device probe, to avoid redoing the
calculation for each access.  Second patch adds error messages
for easier troubleshooting.  Next patch adds helpers which will
take care of address conversions to reach into EMU cache.
Subsequently users are migrated from the raw CPP API to the new RTsym
helpers.  Finally we add support for reading absolute symbols.

To enable easier FW distribution NFP can now automatically
select between FW stored on the flash and loaded from the
kernel.

If FW loading policy is set to auto it will compare the
versions of FW from the host and from the flash and load
the newer one.  If FW type doesn't match (e.g. one advanced
application vs another) the FW from the host takes precedence,
unless one of them is the basic NIC firmware, in which case
the non-basic-NIC FW is selected.

This automatic selection mechanism requires we inform user
what the verdict was.  Print a message to the logs explaining
the decision and the reason.

100GbE Intel Wired LAN Driver Updates 2018-08-28

This series contains new features and implementation updates for the
ice driver.

Anirudh reworks the current flex programming logic to add support for
a second flex descriptor profile.  Updated the transmit scheduler
code to handle changes to the spec, specifically the firmware expects
a 4KB buffer at all times so fix the default scheduler topology buffer
size.  Also the maximum children per node per layer is replaced by
maximum sibling group size.  Adds a check to ensure a reset is not in
progress before exercising a control queue operation.  Refactored the
switch rule management functions and structures to simply the logic and
to add a common function to search for a rule entry and add a new rule
entry.  Refactored the VSI allocation, deletion and rebuild flow so that
on reset we can restore all the filters that were previously added.  Did
some spring cleaning of define names and macros.

Dan updates the admin queue command for requesting resource ownership
to the latest specification by adding new enum's and change the locks.

Zhenning optimizes the driver by using the existing buffer in a
structure directly versus a local array.

Chinh implements handlers for ethtool for get and set link settings.

Sudheer implements transmit hang/timeout detection and malicious driver
detection in the driver.

Md Fahad Iqbal implements the get and set bridge mode operations.

Hieu adds the ability for firmware logging during initialization.

10GbE Intel Wired LAN Driver Updates 2018-08-28

This series contains updates to ixgbe and ixgbevf only.

Sebastian adds support for firmware NVM recovery mode, which logs a
message when errors are detected and un-registers the device.  Also
fixed RSS type recognition with VF to VF communication.

Shannon Nelson implements IPsec hardware offload for VF devices in
Intel's 10GbE x540 family of Ethernet devices.

The IPsec HW offload feature has been in the x540/Niantic family of
network devices since their release in 2009, but there was no Linux
kernel support for the offload until 2017.  After the XFRM code added
support for the offload last year, the HW offload was added to the ixgbe
PF driver.

Since the related x540 VF device uses same setup as the PF for implementing
the offload, adding the feature to the ixgbevf seemed like a good idea.
In this case, the PF owns the device registers, so the VF simply packages
up the request information into a VF<->PF message and the PF does the
device configuration.

There seems to be a problem in the x540's internal switch wherein if SR-IOV
mode is enabled and an offloaded IPsec packet is sent to a local VF,
the packet is silently dropped.  This might never be a problem as it is
somewhat a corner case, but if someone happens to be using IPsec offload
from the PF to a VF that just happens to get migrated to the local box,
communication will mysteriously fail.

Not good.

A simple way to protect from this is to simply not allow any IPsec offloads
for outgoing packets when num_vfs != 0.  This doesn't help any offloads that
were created before SR-IOV was enabled, but we'll get to that later.
