We had a check in the mvpp2_mac_link_down() function (called by phylink)
to avoid disabling the port when link interrupts are used. It turned out
the interrupt can still be used with the port disabled. We can thus
remove this check.

cxgb4/cxgb4vf: VF link state support
This series of patches adds support for ndo_set_vf_link_state in
cxgb4 driver.
Patch 1 implements ndo_set_vf_link_state
Patch 2 reverts the existing force_link_up behaviour for cxgb4vf driver.

net: 64bit support for SO_MAX_PACING_RATE
64bit kernels adopted 64bit type for sk_max_pacing_rate in linux-4.20
We can change how we implement SO_MAX_PACING_RATE socket option

For legacy applications using 32bit variable, SO_MAX_PACING_RATE
has to cap the returned value to 0xFFFFFFFF, meaning that
rates above 34.35 Gbit are capped.
This patch allows applications to read socket pacing rate
at full resolution, if they provide a 64bit variable to store it,
and the kernel is 64bit.

By adding a check for an optional key/value pair to the test case
data, individual test cases may be skipped to prevent tdc from
aborting a test run due to setup or teardown failure.
If a test case is skipped, it will still appear in the results
output to allow for a consistent number of executed tests in each
run. However, the test will be marked as skipped.
This support for skipping extends to any plugins that may generate
additional results for each executed test.

mlxsw: spectrum_acl: Split rehash work into chunks
Jiri says:
When rehash happens on a vregion with many rules and they are being
migrated, it might take significant time to finish the job. During that
time vregion->lock is taken which prevents rules from being
added/deleted from the vregion.
Aim of this patchset is to allow to interrupt migration of rules during
rehash, reschedule and give chance for rules to be added/deleted. Then
continue migration in another execution of scheduled work.

====================
nfp: control processor DMA support and RJ45
This series starts with adding support for reporting twisted pair
media type in ethtool.
Remaining patches add support for using DMA with the control/service
processor. Currently we always copy the command data into card's
memory. DMA support allows us to have the NSP read the data from
host memory by itself. Unfortunately, the FW loading and flashing
cannot directly map the buffers for DMA because (a) the firmware
ABI returns const buffers, and (b) the buffers may be vmalloc()ed
in many mysterious/unmappable way. So just bite the bullet -
allocate new host buffer for the command and copy.
As Dirk explains, the NSP now supports updating all FWs at once
which means the max flashing time grew significantly. He bumps
the max wait to avoid timeouts.

The management firmware now supports being passed a bundle with
multiple components to be stored in flash at once. This makes it
easier to update all components to a known state with a single
user command, however, this also has the potential to increase
the time required to perform the update significantly.
The management firmware only updates the components out of a bundle
which are outdated, however, we need to make sure we can handle
the absolute worst case where a CPLD update can take a long time
to perform.
We set a very conservative total timeout of 900s which already
adds a contingency.

Newer versions of NSP can access host memory. Simplest access
type requires all data to be in one contiguous area. Since we
don't have the guarantee on where callers of the NSP ABI will
allocate their buffers we allocate a bounce buffer and copy

The comphy driver for Armada 3700 by Miquèl Raynal (which is currently
in linux-next) does not actually set comphy mode when phy_set_mode_ext
is called. The mode is set at next call of phy_power_on.
Update the driver to semantics similar to mvpp2: helper
mvneta_comphy_init sets comphy mode and powers it on.
When mode is to be changed in mvneta_mac_config, first power the comphy
off, then call mvneta_comphy_init (which sets the mode to new one).
Only do this when new mode is different from old mode.
This should also work for Armada 38x, since in that comphy driver
methods power_on and power_off are unimplemented.
