In preparation for getting rid of switchdev_ops, create a dedicated NDO
operation for getting the port's parent identifier. There are
essentially two classes of drivers that need to implement getting the
port's parent ID which are VF/PF drivers with a built-in switch, and
pure switchdev drivers such as mlxsw, ocelot, dsa etc.
We introduce a helper function: dev_get_port_parent_id() which supports
recursion into the lower devices to obtain the first port's parent ID.
Convert the bridge, core and ipv4 multicast routing code to check for
such ndo_get_port_parent_id() and call the helper function when valid
before falling back to switchdev_port_attr_get(). This will allow us to
convert all relevant drivers in one go instead of having to implement
both switchdev_port_attr_get() and ndo_get_port_parent_id() operations,
then get rid of switchdev_port_attr_get().

If the system was booted using a device tree and if the device tree
contains a MAC address, use it instead of reading one from the EEPROM.
This is useful in situations where the EEPROM isn't properly programmed
or where the firmware wants to override the existing MAC address.

Instead of allocating page fragments via the network stack,
use the page allocator directly. For now, we consume one page
for each Rx buffer.
With the new memory model we are free to consider adding more
XDP support.
Performance decreases slightly in some IP forwarding cases.
No visible effect on termination traffic. The driver memory
footprint increases as a result of this change, but it is
still small enough to not really matter.
Another side effect is that now Rx buffer alignment requirements
are naturally satisfied without any additional actions needed.
Remove alignment related code, except in the buffer layout
information conveyed to MC, as hardware still needs to know the
alignment value we guarantee.

====================
add flow_rule infrastructure
This patchset, as is, allows us to reuse the driver codebase to
configure ACL hardware offloads for the ethtool_rxnfc and the TC flower
interfaces. A few clients for this infrastructure are presented, such as
the bcm_sf2 and the qede drivers, for reference. Moreover all of the
existing drivers in the tree are converted to use this infrastructure.
This patchset is re-using the existing flow dissector infrastructure
that was introduced by Jiri Pirko et al. so the amount of abstractions
that this patchset adds are minimal. Well, just a few wrapper structures
for the selector side of the rules. And, in order to express actions,
this patchset exposes an action API that is based on the existing TC
action infrastructure and what existing drivers already support on that
front.
v7: This patchset is a rebase on top of the net-next tree, after
addressing questions and feedback from driver developers in the
last batch.

The qede driver supports for ethtool_rx_flow_spec and flower, both
codebases look very similar.
This patch uses the ethtool_rx_flow_rule() infrastructure to remove the
duplicated ethtool_rx_flow_spec parser and consolidate ACL offload
support around the flow_rule infrastructure.
Furthermore, more code can be consolidated by merging
qede_add_cls_rule() and qede_add_tc_flower_fltr(), these two functions
also look very similar.
This driver currently provides simple ACL support, such as 5-tuple
matching, drop policy and queue to CPU.
Drivers that support more features can benefit from this infrastructure
to save even more redundant codebase.

This patch adds a function to translate the ethtool_rx_flow_spec
structure to the flow_rule representation.
This allows us to reuse code from the driver side given that both flower
and ethtool_rx_flow interfaces use the same representation.
This patch also includes support for the flow type flags FLOW_EXT,
FLOW_MAC_EXT and FLOW_RSS.
The ethtool_rx_flow_spec_input wrapper structure is used to convey the
rss_context field, that is away from the ethtool_rx_flow_spec structure,
and the ethtool_rx_flow_spec structure.

These actions need to be added to support the ethtool_rx_flow interface.
The queue action includes a field to specify the RSS context, that is
set via FLOW_RSS flow type flag and the rss_context field in struct
ethtool_rxnfc, plus the corresponding queue index. FLOW_RSS implies that
rss_context is non-zero, therefore, queue.ctx == 0 means that FLOW_RSS
was not set. Also add a field to store the vf index which is stored in

This patch wraps the dissector key and mask - that flower uses to
represent the matching side - around the flow_match structure.
To avoid a follow up patch that would edit the same LoCs in the drivers,
this patch also wraps this new flow match structure around the flow rule
object. This new structure will also contain the flow actions in follow
up patches.
This introduces two new interfaces:
bool flow_rule_match_key(rule, dissector_id)
that returns true if a given matching key is set on, and:
flow_rule_match_XYZ(rule, &match);
To fetch the matching side XYZ into the match container structure, to
retrieve the key and the mask with one single call.

Intel Wired LAN Driver Updates 2019-02-05
This series contains updates to igc, e1000e, ixgbe, fm10k and driver
documentation.
Kai-Heng Feng fixes an e1000e issue where the Wake-On-LAN settings where
being set incorrectly during a system suspend.
Sasha addresses community feedback on the igc driver and provides a
number of code cleanups to remove either unreachable or unused code. In
addition, added basic ethtool support for the igc driver.
Mike Rapoport fixes the formatting of the kernel driver documentation so
that the title is properly formatted and does not get lumped with the
document sections in the HTML kernel documents generated.
Jiri Kosina updates a hard coded RAR entries value with the existing
define IXGBE_82599_RAR_ENTRIES.
Jake fixes up whitespace in the fm10k driver.
Konstantin Khlebnikov fixes an issue where in some cases, the e1000e
driver will continually reset during a system boot because the watchdog
task sees items in the transmit buffer but the carrier is off (trying to
establish link) causing the device reset to flush the buffer. To
resolve, just move this check/flush into the watchdog section for when
the carrier is off.
Todd bumps the igb driver version to reflect the recent driver changes.

Sven Auhagen reports that if he changes a SFP+ module for a SFP module
on the Macchiatobin Single Shot, the link does not come back up. For
Sven, it is as easy as:
- Insert a SFP+ module connected, and use ping6 to verify link is up.
- Remove SFP+ module
- Insert SFP 1000base-X module use ping6 to verify link is up: Link
up event did not trigger and the link is down
but that doesn't show the problem for me. Locally, this has been
reproduced by:
- Boot with no modules.
- Insert SFP+ module, confirm link is up.
- Replace module with 25000base-X module. Confirm link is up.
- Set remote end down, link is reported as dropped at both ends.
- Set remote end up, link is reported up at remote end, but not local
end due to lack of link interrupt.
Fix this by setting up both GMAC and XLG interrupts for port 0, but
only unmasking the appropriate interrupt according to the current mode
set in the mac_config() method. However, only do the mask/unmask
dance when we are really changing the link mode to avoid missing any
link interrupts.

Use the phy_interface_mode_is_8023z() helper for detecting interface
modes that use 802.3z serial encoding. This is equivalent to testing
for both 1000base-X and 2500base-X.

====================
nixge: Fixed-link support
This series adds fixed-link support to nixge.
The first patch corrects the binding to correctly reflect
hardware that does not come with MDIO cores instantiated.
The second patch adds fixed link support to the driver.
The third patch updates the binding document with the now
optional (formerly required) phy-handle property and references
the fixed-link docs.

Update device-tree binding with fixed-link support.
With fixed-link support the formerly required property 'phy-handle'
is now optional if 'fixed-link' child is present.
