====================
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.

- 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

This fixes a regression introduced by
commit 0d2e778e38
"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.

The reason is RFC 4541 is not a standard but suggestive. Currently we
will elect 0.0.0.0 as Querier if there is no ip address configured on
bridge. If we do not add the port which recives query with source
0.0.0.0 to router list, the IGMP reports will not be about to forward
to Querier, IGMP data will also not be able to forward to dest.

Just like commit e2ba732a16 ("selftests: fib_tests: sleep after
changing carrier"), wait one second to allow linkwatch to propagate the
carrier change to the stack.
There are two sets of carrier tests. The first slept after the carrier
was set to off, and when the second set ran, it was likely that the
linkwatch would be able to run again without much delay, reducing the
likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a
loop, you will quickly notice the failures.
Sleeping on the second set of tests make the failures go away.

This patchset adds support for new port types and speeds for Spectrum-2.
Patch #1 + #2 removes an unsupported PTYS field and a duplicate link
mode entry.
Patch #3 queries port's connector type from firmware instead of deriving
it from port admin state.
Patch #4 renames functions which relate to port type-speed to be
Spectrum-1 specific.
Patch #5 defines port type-speed operations and applies it for
Spectrum-1.
Patch #6 + #7 are small renaming and cosmetic changes.
Patch #8 adds new port type-speed fields for PTYS register. These new
fields extend the existing ones in order to support more types and
speeds.
Patch #9 adds Spectrum-2 support for port type-speed operations.
Patch #10 adds Spectrum-2 new port types and speeds.
For Spectrum-2, the user must configure all the types per speed if he /
she wants a specific speed to be advertised. For example, if the user
wants to advertise 100Gbps 4-lanes speed, the following ethtool bits
should be advertised:

We are not specifying an explicit format argument but instead passing a
string litteral which causes these two warnings to show up:
