bfcccfe78b netdevsim: drop code duplicated by a merge
Looks like the port adding loop makes a re-appearance on net-next
after net was merged back into it (even though it doesn't feature
in the merge diff).

The ports are already added in nsim_dev_create() so when we try
to add them again get EEXIST, and see:

netdevsim: probe of netdevsim0 failed with error -17

in the logs. When we remove the loop again the nsim_dev_probe()
and nsim_dev_remove() become a wrapper of nsim_dev_create() and
nsim_dev_destroy(). Remove this layer of indirection.

9647722bef r8152: Add macpassthru support for ThinkPad Thunderbolt 3 Dock Gen 2
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

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.

v2: Fixed up commit id references in patch 5's description to align with
    how commit id's should be referenced.

07066d9dc3 ixgbe: protect TX timestamping from API misuse
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.

Similar-to:

780e354dcd ixgbe: Make use of cpumask_local_spread to improve RSS locality
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.

Typically, for x86 and standard MTU size we will end up with 192 bytes

can dedicate it for XDP purposes.

Furthermore, introduce the Rx ring flag for indicating whether build_skb

7237f5b0db ice: introduce legacy Rx flag
Add an ethtool "legacy-rx" priv flag for toggling the Rx path. This
control knob will be mainly used for build_skb usage as well as buffer
size/MTU manipulation.

In preparation for adding build_skb support in a way that it takes
care of how we set the values of max_frame and rx_buf_len fields of
struct ice_vsi. Specifically, in this patch mentioned fields are set to
values that will allow us to provide headroom and tailroom in-place.

This can be mostly broken down onto following:
- for legacy-rx "on" ethtool control knob, old behaviour is kept;
- for standard 1500 MTU size configure the buffer of size 1536, as
  network stack is expecting the NET_SKB_PAD to be provided and
  NET_IP_ALIGN can have a non-zero value (these can be typically equal
  to 32 and 2, respectively);
- for larger MTUs go with max_frame set to 9k and configure the 3k
  buffer in case when PAGE_SIZE of underlying arch is less than 8k; 3k
  buffer is implying the need for order 1 page, so that our page
  recycling scheme can still be applied;

With that said, substitute the hardcoded ICE_RXBUF_2048 and PAGE_SIZE
values in DMA API that we're making use of with rx_ring->rx_buf_len and
ice_rx_pg_size(rx_ring). The latter is an introduced helper for
determining the page size based on its order (which was figured out via
ice_rx_pg_order). Last but not least, take care of truesize calculation.

In the followup patch the headroom/tailroom computation logic will be
introduced.

This change aligns the buffer and frame configuration with other Intel
drivers, most importantly with iavf.

2d4238f556 ice: Add support for AF_XDP
Add zero copy AF_XDP support.  This patch adds zero copy support for
Tx and Rx; code for zero copy is added to ice_xsk.h and ice_xsk.c.

For Tx, implement ndo_xsk_wakeup. As with other drivers, reuse
existing XDP Tx queues for this task, since XDP_REDIRECT guarantees
mutual exclusion between different NAPI contexts based on CPU ID. In
turn, a netdev can XDP_REDIRECT to another netdev with a different
NAPI context, since the operation is bound to a specific core and each
core has its own hardware ring.

For Rx, allocate frames as MEM_TYPE_ZERO_COPY on queues that AF_XDP is
enabled.

0891d6d4b1 ice: Move common functions to ice_txrx_lib.c
In preparation of AF XDP, move functions that will be used both by skb and
zero-copy paths to a new file called ice_txrx_lib.c.  This allows us to
avoid using ifdefs to control the staticness of said functions.

Move other functions (ice_rx_csum, ice_rx_hash and ice_ptype_to_htype)
called only by the moved ones to the new file as well.

0c65b2b90d net: of_get_phy_mode: Change API to solve int/unit warnings
Before this change of_get_phy_mode() returned an enum,
phy_interface_t. On error, -ENODEV etc, is returned. If the result of
the function is stored in a variable of type phy_interface_t, and the
compiler has decided to represent this as an unsigned int, comparision
with -ENODEV etc, is a signed vs unsigned comparision.

Fix this problem by changing the API. Make the function return an
error, or 0 on success, and pass a pointer, of type phy_interface_t,
where the phy mode should be stored.

v2:
Return with *interface set to PHY_INTERFACE_MODE_NA on error.
Add error checks to all users of of_get_phy_mode()
Fixup a few reverse christmas tree errors

62bdc8fd1c r8169: fix wrong PHY ID issue with RTL8168dp
As reported in [0] at least one RTL8168dp version has problems
establishing a link. This chip version has an integrated RTL8211b PHY,
however the chip seems to report a wrong PHY ID, resulting in a wrong
PHY driver (for Generic Realtek PHY) being loaded.
Work around this issue by adding a hook to r8168dp_2_mdio_read()
for returning the correct PHY ID.

Since it became possible for the DSA core to use a CPU port different
than 8, our bcm_sf2_imp_setup() function was broken because it assumes
that registers are applicable to port 8. In particular, the port's MAC
is going to stay disabled, so make sure we clear the RX_DIS and TX_DIS
bits if we are not configured for port 8.
