This patch adds pedit_headers_action structure to store the result of
parsing tc pedit actions. Then, it calls alloc_tc_pedit_action() to
populate the mlx5e hardware intermediate representation once all actions
have been parsed.

This patch comes in preparation for the new flow_action infrastructure,
where each packet mangling comes in an separated action, ie. not packed
as in tc pedit.

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.

I'm seeing series of e1000e resets (sometimes endless) at system boot

As result e1000_watchdog_task sees used tx buffer while carrier is off
and start this reset cycle again.

e1000e sets different WoL settings in system suspend callback and

The suspend direct complete optimization leaves e1000e in runtime

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.

All users of the fixed_phy_add() pass -1 as GPIO number
to the fixed phy driver, and all users of fixed_phy_register()
pass -1 as GPIO number as well, except for the device
tree MDIO bus.

Any new users should create a proper device and pass the
GPIO as a descriptor associated with the device so delete
the GPIO argument from the calls and drop the code looking
requesting a GPIO in fixed_phy_add().

In fixed phy_register(), investigate the "fixed-link"
node and pick the GPIO descriptor from "link-gpios" if
this property exists. Move the corresponding code out
of of_mdio.c as the fixed phy code anyways requires
OF to be in use.

Add support for the RX checksum offload. This is enabled by default and
may be disabled and re-enabled using 'ethtool':

# ethtool -K eth0 rx off
# ethtool -K eth0 rx on

Some Ether MACs provide a simple checksumming scheme which appears to be
completely compatible with CHECKSUM_COMPLETE: sum of all packet data after
the L2 header is appended to packet data; this may be trivially read by
the driver and used to update the skb accordingly. The same checksumming
scheme is implemented in the EtherAVB MACs and now supported by the 'ravb'
driver.

In terms of performance, throughput is close to gigabit line rate with the
RX checksum offload both enabled and disabled.  The 'perf' output, however,
appears to indicate that significantly less time is spent in do_csum() --
this is as expected.

Commit 62e04b7e ("sh_eth: rename 'sh_eth_cpu_data::hw_crc'") renamed
the field to 'hw_checksum' for the Ether DMAC "intelligent checksum",
however some Ether MACs implement a simpler checksumming scheme, so that
name now seems misleading. Rename that field to 'csmr' as the "intelligent
checksum" is always controlled by the CSMR register.

Add __cold to the netdev_<level> logging functions similar to
the use of __cold in the generic printk function.

Using __cold moves all the netdev_<level> logging functions
out-of-line possibly improving code locality and runtime
performance.
