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().

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.

    addressing questions and feedback from driver developers in the

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.

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

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

Mike Rapoport fixes the formatting of the kernel driver documentation so
that the title is properly formatted and does not get lumped with the

Jiri Kosina updates a hard coded RAR entries value with the existing

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.
