The PPv2 controller is able to support 2.5G speeds, allowing to use
2.5GBASET in conjunction with PHYs that use 2500BASEX as their MII
interface when using this mode.

As per 802.3bz, if bit 14 of (1.11) "PMA Extended Abilities" indicates
whether or not we should read register (1.21) "2.52/5G PMA Extended
Abilities", which contains information on the support of 2.5GBASET and
5GBASET.
After testing on several variants of PHYS of this family, it appears
that bit 14 in (1.11) isn't always set when it should be.
PHYs 88X3310 (on MacchiatoBin) and 88E2010 do support 2.5G and 5GBASET,
but don't have 1.11.14 set. Their register 1.21 is filled with the
correct values, indicating 2.5G and 5G support.
PHYs 88E2110 do have their 1.11.14 bit set, as it should.

The Marvell Alaska family of PHYs supports 2.5GBaseT and 5GBaseT modes,
as defined in the 802.3bz specification.
Upon establishing a 2.5GBASET link, the PHY will reconfigure it's MII
interface to 2500BASEX.
At 5G, the PHY will reconfigure it's interface to 5GBASE-R, but this
mode isn't supported by any MAC for now.
This was tested with :
- The 88X3310, which is on the MacchiatoBin
- The 88E2010, an Alaska PHY that has no fiber interfaces, and is
limited to 5G maximum speed.

The Alaska family of 10G PHYs has more abilities than the ones listed in
PHY_10GBIT_FULL_FEATURES, the exact list depending on the model.
Make use of the newly introduced .get_features call to build this list,
using genphy_c45_pma_read_abilities to build the list of supported
linkmodes, and adding autoneg ability based on what's reported by the AN
MMD.
.config_init is still used to validate the interface_mode.

The current code reports a link as up if all devices (except a few
blacklisted ones) report the link as up. This breaks Aquantia AQCS109
for lower speeds because on this PHY the PCS link status reflects a
10G link only. For Marvell there's a similar issue, therefore PHYXS
device isn't checked.
There may be more PHYs where depending on the mode the link status
of only selected devices is relevant.
For now it seems to be sufficient to check the link status of the
PMAPMD device only. Leave the loop in the code to be prepared in
case we have to add functionality to check more than one device,
depending on the mode.
Successfully tested on a board with an AQCS109.

Add tests for unlocked flower classifier implementation
Implement tests for tdc testsuite to verify concurrent rules update with
rtnl-unlocked flower classifier implementation. The goal of these tests
is to verify general flower classifier correctness by updating filters
on same classifier instance in parallel and to verify its atomicity by
concurrently updating filters in same handle range. All three filter
update operations (add, replace, delete) are tested.
Existing script tdc_batch.py is re-used for batch file generation. It is
extended with several optional CLI arguments that are needed for
concurrency tests. Thin wrapper tdc_multibatch.py is implemented on top
of tdc_batch.py to simplify its usage when generating multiple batch
files for several test configurations.
Parallelism in tests is implemented by running multiple instances of tc
in batch mode with xargs tool. Xargs is chosen for its ease of use and
because it is available by default on most modern Linux distributions.

Extend tdc_batch.py with several optional CLI arguments that are used for
implementation of concurrency tests in following patches in this set:
- Add optional argument to specify range of filter handles used in batch
file [fitler_handle, filter_handle+number). This is needed for testing
filter deletion where it is necessary to know exact handles of configured
filters.
- Add optional argument to specify filter operation type (possible values
are ['add', 'del', 'replace']) instead of hardcoded "add" value. This
allows generation of batches for filter addition, deletion and
replacement.
- Add optional argument to allow user to change mac address prefix that is
used for all filters in batch. This is necessary to allow generating
multiple batches with unique flower classifier keys.

and allows them to pass into the stack. After patch [2] no placeholder

ACPICA commit a4849944e80f97970e99843f4975850753584a4e
This change adds PCC operation region support in the AML interpreter
and a default handler for acpiexec. According to the specification,
the PCC operation region performs a transaction when the COMD field
is written. This allows ASL to write data to other fields before
sending the data.
In order to accommodate this protocol, a temorary buffer is added
to the regionfield object to accumulate writes. If any offset that
spans COMD is written, the temporary buffer is sent to the PCC
operation region handler to be processed.
This change also renames the PCC keyword to platform_comm_channel.

This fixes a regression introduced by
commit 0d2e778e38e0ddffab4bb2b0e9ed2ad5165c4bf7
"net: phy: replace PHY_HAS_INTERRUPT with a check for
config_intr and ack_interrupt".
This assumes that a PHY cannot trigger interrupt unless
it has .config_intr() or .ack_interrupt() implemented.
A later patch makes the code assume both need to be
implemented for interrupts to be present.
But this PHY (which is inside a DSA) will happily
fire interrupts without either callback.
Implement dummy callbacks for .config_intr() and
.ack_interrupt() in the phy header to fix this.
Tested on the RTL8366RB on D-Link DIR-685.
