====================
net: ks8851: Unify KS8851 SPI and MLL drivers

The KS8851SNL/SNLI and KS8851-16MLL/MLLI/MLLU are very much the same pieces
of silicon, except the former has an SPI interface, while the later has a
parallel bus interface. Thus far, Linux has two separate drivers for each
and they are diverging considerably.

This series unifies them into a single driver with small SPI and parallel
bus specific parts. The approach here is to first separate out the SPI
specific parts into a separate file, then add parallel bus accessors in
another separate file and then finally remove the old parallel bus driver.
The reason for replacing the old parallel bus driver is because the SPI
bus driver is much higher quality.

Note that I dropped "net: ks8851: Drop define debug and pr_fmt()" for now,
will send it separatelly later.

Merge branch 'vmxnet3-upgrade-to-version-4'

Ronak Doshi says:

====================
vmxnet3: upgrade to version 4

vmxnet3 emulation has recently added several new features which includes
offload support for tunnel packets, support for new commands the driver
can issue to emulation, change in descriptor fields, etc. This patch
series extends the vmxnet3 driver to leverage these new features.

Compatibility is maintained using existing vmxnet3 versioning mechanism as
follows:
 - new features added to vmxnet3 emulation are associated with new vmxnet3
   version viz. vmxnet3 version 4.
 - emulation advertises all the versions it supports to the driver.
 - during initialization, vmxnet3 driver picks the highest version number
 supported by both the emulation and the driver and configures emulation
 to run at that version.

In particular, following changes are introduced:

Patch 1:
  This patch introduces utility macros for vmxnet3 version 4 comparison
  and updates Copyright information.

Patch 2:
  This patch implements get_rss_hash_opts and set_rss_hash_opts methods
  to allow querying and configuring different Rx flow hash configurations
  which can be used to support UDP/ESP RSS.

Patch 3:
  This patch introduces segmentation and checksum offload support for
  encapsulated packets. This avoids segmenting and calculating checksum
  for each segment and hence gives performance boost.

Patch 4:
  With all vmxnet3 version 4 changes incorporated in the vmxnet3 driver,
  with this patch, the driver can configure emulation to run at vmxnet3
  version 4.

Changes in v3 -> v4:
   - Replaced BUG_ON() with WARN_ON_ONCE()

Changes in v2 -> v3:
   - fixed get_rss_hash_opts to return correct values for udp rss

Changes in v2:
   - Fixed compilation issue due to missing closed brace
   - added fallthrough comment

vmxnet3: add geneve and vxlan tunnel offload support

Vmxnet3 version 3 device supports checksum/TSO offload. Thus, vNIC to
pNIC traffic can leverage hardware checksum/TSO offloads. However,
vmxnet3 does not support checksum/TSO offload for Geneve/VXLAN
encapsulated packets. Thus, for a vNIC configured with an overlay, the
guest stack must first segment the inner packet, compute the inner
checksum for each segment and encapsulate each segment before
transmitting the packet via the vNIC. This results in significant
performance penalty.

This patch will enhance vmxnet3 to support Geneve/VXLAN TSO as well as
checksum offload.

100GbE Intel Wired LAN Driver Updates 2020-05-27

This series contains updates to the ice driver only.

Jesse fixes a number of issues, starting with fixing the remaining
signed versus unsigned comparison issues.  Cleaned up an unused code
define.  Fixed the implementation of the manage MAC write command, to
simplify it by using a simple array to represent the MAC address when
writing it.

Paul fixes the setting of the VF default LAN address, by removing a
check that assumed that the address had been deleted and zeroed.

Surabhi prevents a memory leak on filter management initialization
failures and during queue initialization and buffer allocation failures.

Brett adds additional receive error counters that are reported by
ethtool.  Fixed the enabling and disabling of VLAN stripping when the
PVID has been set.

Evan fixes a race condition between the firmware and software, which can
occur between the admin queue setup and the first command sent.

Marta fixes the driver when XDP transmit rings are destroyed, also make
sure the XDP transmit queues are also destroyed.  Update the statistics
when XDP transmit programs are loaded and packets are sent.  Changed the
number of XDP transmit queues to match the number of receive queues,
instead of matching the number of transmit queues.

Bruce avoids undefined behavior by not writing the 8-bit element
init_q_state with the associated internal-to-hardware field which is
122-bits.

Anirudh (Ani) refactors the receive checksum checks.

Krzysztof notifies the user if the fill queue is not long enough to
prepare all buffers before packet processing starts and allocates the
buffers during the NAPI poll.

====================
remove most callers of kernel_setsockopt v3

this series removes most callers of the kernel_setsockopt functions, and

sockopt directly using a normal kernel function call with type safety and
all the other benefits of not having a function call.

In some cases these functions seem pretty heavy handed as they do
a lock_sock even for just setting a single variable, but this mirrors
the real setsockopt implementation unlike a few drivers that just set

Changes since v2:
 - drop the separately merged kernel_getopt_removal

 - add an additional ACK for the rxrpc changes

Summary:
--------
Problem statement:
------------------
Currently in above topology, when netfailover device is configured using
VFs and eswitch VF representors, and when traffic fails over to stand-by
VF which is exposed using macvtap device to guest VM, eswitch fails to
switch the traffic to the stand-by VF representor. This occurs because
there is no knowledge at eswitch level of the stand-by representor
device.

Solution:
---------
Using standard bonding driver, a bond netdevice is created over VF
representor device which is used for offloading tc rules.
Two VF representors are bonded together, one for the passthrough VF
device and another one for the stand-by VF device.
With this solution, mlx5 driver listens to the failover events
occuring at the bond device level to failover traffic to either of
the active VF representor of the bond.

a. VM with netfailover device of VF pass-thru (PT) device and virtio-net
   paravirtualized device with same MAC-address to handle failover
   traffics at VM level.

b. Host bond is active-standby mode, with the lower devices being the VM
   VF PT representor, and the representor of the 2nd VF to handle
   failover traffics at Hypervisor/V-Switch OVS level.
   - During the steady state (fast datapath): set the bond active
     device to be the VM PT VF representor.
   - During failover: apply bond failover to the second VF representor
     device which connects to the VM non-accelerated path.

c. E-Switch ingress/egress ACL tables to support failover traffics at
   E-Switch level
   I. E-Switch egress ACL with forward-to-vport rule:
     - By default, eswitch vport egress acl forward packets to its
       counterpart NIC vport.
     - During port failover, the egress acl forward-to-vport rule will
       be added to e-switch vport of passive/in-active slave VF
representor
       to forward packets to other e-switch vport ie. the active slave
       representor's e-switch vport to handle egress "failover"
traffics.
     - Using lower change netdev event to detect a representor is a
       lower
       dev (slave) of bond and becomes active, adding egress acl
       forward-to-vport rule of all other slave netdevs to forward to
this
       representor's vport.
     - Using upper change netdev event to detect a representor unslaving
       from bond device to delete its vport's egress acl forward-to-vport
       rule.

   II. E-Switch ingress ACL metadata reg_c for match
     - Bonded representors' vorts sharing tc block have the same
       root ingress acl table and a unique metadata for match.
     - Traffics from both representors's vports will be tagged with same
       unique metadata reg_c.
     - Using upper change netdev event to detect a representor
       enslaving/unslaving from bond device to setup shared root ingress
       acl and unique metadata.

2) From Alex Vesker (2): Slpit RX and TX lock for parallel rule insertion in
software steering

3) Eli Britstein (2): Optimize performance for IPv4/IPv6 ethertype use the HW

ice: Check UMEM FQ size when allocating bufs

If a UMEM is present on a queue when an interface/queue pair is being
enabled, the driver will try to prepare the Rx buffers in advance to
improve performance. However, if fill queue is shorter than HW Rx ring,
the driver will report failure after getting the last address from the
fill queue.

This still lets the driver process the packets correctly during the NAPI
poll, but leads to a constant NAPI rescheduling. Not allocating the
buffers in advance would result in a potential performance decrease.

Commit cda841f430ee ("xsk: Add API to check for available entries in FQ")
provides an API that lets drivers check the number of addresses that the
fill queue holds.

Notify the user if fill queue is not long enough to prepare all buffers
before packet processing starts, and allocate the buffers during the
NAPI poll. If the fill queue size is sufficient, prepare Rx buffers in
