ThinkPad Thunderbolt 3 Dock Gen 2 is another docking station that uses
RTL8153 based USB ethernet.

The device supports macpassthru, but it failed to pass the test of -AD,
-BND and -BD. Simply bypass these tests since the device supports this
feature just fine.

Also the ACPI objects have some differences between Dell's and Lenovo's,
so make those ACPI infos no longer hardcoded.

100GbE Intel Wired LAN Driver Updates 2019-11-04

This series contains updates to the ice driver only.

Anirudh refactors the code to reduce the kernel configuration flags and
introduces ice_base.c file.

Maciej does additional refactoring on the configuring of transmit
rings so that we are not configuring per each traffic class flow.
Added support for XDP in the ice driver.  Provides additional
re-organizing of the code in preparation for adding build_skb() support
in the driver.  Adjusted the computational padding logic for headroom
and tailroom to better support build_skb(), which also aligns with the
logic in other Intel LAN drivers.  Added build_skb support and make use
of the XDP's data_meta.

Krzysztof refactors the driver to prepare for AF_XDP support in the
driver and then adds support for AF_XDP.

v2: Updated patch 3 of the series based on community feedback with the
    following changes...
    - return -EOPNOTSUPP instead of ENOTSUPP for too large MTU which makes
      it impossible to attach XDP prog
    - don't check for case when there's no XDP prog currently on interface
      and ice_xdp() is called with NULL bpf_prog; this happens when user
      does "ip link set eth0 xdp off" and no prog is present on VSI; no need
      for that as it is handled by higher layer
    - drop the extack message for unknown xdp->command
    - use the smp_processor_id() for accessing the XDP Tx ring for XDP_TX
      action
    - don't leave the interface in downed state in case of any failure
      during the XDP Tx resources handling
    - undo rename of ice_build_ctob
    The above changes caused a ripple effect in patches 4 & 5 to update
    references to ice_build_ctob() which are now build_ctob()

10GbE Intel Wired LAN Driver Updates 2019-11-04

This series contains old Halloween candy updates, yet still sweet, to
fm10k, ixgbe and i40e.

Jake adds the missing initializers for a couple of the TLV attribute
macros.  Added support for capturing and reporting statistics for all of
the VFs in a given PF.  Lastly, bump the version of the fm10k driver to
reflect the recent changes.

Alex addresses locality issues in the ixgbe driver when it is loaded on
a system supporting multiple NUMA nodes.

Manjunath Patil provides changes to the ixgbe driver, similar to those
made to igb, to prevent transmit packets to request a hardware timestamp
when the NIC has not been setup via the SIOCSHWTSTAMP ioctl.

Alice adds support for x710 by adding the missing device id's in the
appropriate places to ensure all the features are enabled in i40e.

Jesse adds support for VF stats gathering in the i40e via the kernel
via ndo_get_vf_stats function.

HW timestamping can only be requested for a packet if the NIC is first
setup via ioctl(SIOCSHWTSTAMP). If this step was skipped, then the ixgbe
driver still allowed TX packets to request HW timestamping. In this
situation, we see 'clearing Tx Timestamp hang' noise in the log.

Fix this by checking that the NIC is configured for HW TX timestamping
before accepting a HW TX timestamping request.

This patch is meant to address locality issues present in the ixgbe driver
when it is loaded on a system supporting multiple NUMA nodes and more CPUs
then the device can map in a 1:1 fashion. Instead of just arbitrarily
mapping itself to CPUs 0-62 it would make much more sense to map itself to
the local CPUs first, and then map itself to any remaining CPUs that might
be used.

The first effect of this is that queue 0 should always be allocated on the
local CPU/NUMA node. This is important as it is the default destination if
a packet doesn't match any existing flow director filter or RSS rule and as
such having it local should help to reduce QPI cross-talk in the event of
an unrecognized traffic type.

In addition this should increase the likelihood of the RSS queues being
allocated and used on CPUs local to the device while the ATR/Flow Director
queues would be able to route traffic directly to the CPU that is likely to
be processing it.
