Add four test cases to verify MAB functionality:
* Verify that a locked FDB entry can be generated by the bridge,
preventing a host from communicating via the bridge. Test that user
space can clear the "locked" flag by replacing the entry, thereby
authenticating the host and allowing it to communicate via the bridge.
* Test that an entry cannot roam to a locked port, but that it can roam
to an unlocked port.
* Test that MAB can only be enabled on a port that is both locked and
has learning enabled.
* Test that locked FDB entries are flushed from a port when MAB is
disabled.

The first host interface has by default no interest in receiving packets
MAC DA de:ad:be:ef:13:37, so it might drop them before they hit the tc

As mentioned in the blamed commit, flood_unicast_test() works by
checking the match count on a tc filter placed on the receiving
interface.
But the second host interface (host2_if) has no interest in receiving a
packet with MAC DA de:ad:be:ef:13:37, so its RX filter drops it even
before the ingress tc filter gets to be executed. So we will incorrectly
get the message "Packet was not flooded when should", when in fact, the
packet was flooded as expected but dropped due to an unrelated reason,
at some other layer on the receiving side.
Force h2 to accept this packet by temporarily placing it in promiscuous
mode. Alternatively we could either deliver to its MAC address or use
tcpdump_start, but this has the fewest complications.
This fixes the "flooding" test from bridge_vlan_aware.sh and
bridge_vlan_unaware.sh, which calls flood_test from the lib.

The function get_l3_stats() from the test hw_stats_l3.sh will be useful for
any test that wishes to work with L3 stats. Furthermore, it is easy to
generalize to other HW stats suites (for when such are added). Therefore,
move the code to lib.sh, rewrite it to have the same interface as the other
stats-collecting functions, and generalize to take the name of the HW stats
suite to collect as an argument.

By default, DSA switch ports inherit their MAC address from the DSA
master.
This works well for practical situations, but some selftests like
bridge_vlan_unaware.sh loop back 2 standalone DSA ports with 2 bridged
DSA ports, and require the bridge to forward packets between the
standalone ports.
Due to the bridge seeing that the MAC DA it needs to forward is present
as a local FDB entry (it coincides with the MAC address of the bridge
ports), the test packets are not forwarded, but terminated locally on
br0. In turn, this makes the ping and ping6 tests fail.
Address this by introducing an option to have stable MAC addresses.
When mac_addr_prepare is called, the current addresses of the netifs are
saved and replaced with 00:01:02:03:04:${netif number}. Then when
mac_addr_restore is called at the end of the test, the original MAC
addresses are restored. This ensures that the MAC addresses are unique,
which makes the test pass even for DSA ports.
The usage model is for the behavior to be opt-in via STABLE_MAC_ADDRS,
which DSA should set to true, all others behave as before. By hooking
the calls to mac_addr_prepare and mac_addr_restore within the forwarding
lib itself, we do not need to patch each individual selftest, the only
requirement is that pre_cleanup is called.

A number of mlxsw-specific selftests currently detect whether they are run
on a compatible machine, and bail out silently when not. These tests are
however done in a somewhat impenetrable manner by directly comparing PCI
IDs against a blacklist or a whitelist, and bailing out silently if the
machine is not compatible.
Instead, add a helper, mlxsw_only_on_spectrum(), which allows specifying
the supported machines in a human-readable manner. If the current machine
is incompatible, the helper emits a SKIP message and returns an error code,
based on which the caller can gracefully bail out in a suitable way. This
allows a more readable conditions such as:
mlxsw_only_on_spectrum 2+ || return
Convert all existing open-coded guards to the new helper. Also add two new
guards to do_mark_test() and do_drop_test(), which are supported only on
Spectrum-2+, but the corresponding check was not there.

There are several test cases in the net directory are still using
exit 0 or exit 1 when they need to be skipped. Use kselftest
framework skip code instead so it can help us to distinguish the
return status.
Criterion to filter out what should be fixed in net directory:
grep -r "exit [01]" -B1 | grep -i skip
This change might cause some false-positives if people are running
these test scripts directly and only checking their return codes,
which will change from 0 to 4. However I think the impact should be
small as most of our scripts here are already using this skip code.
And there will be no such issue if running them with the kselftest
framework.

Entries. The label, tc, bos and ttl fields are tested for the first

There are also tests for matching the presence of a label stack entry

In order to reduce the amount of code, all "lse" subcommands are tested

packets are evaluated by all filters. Then, we can verify if each

Provide an example script which can be used as a skeleton for offloading
TCAM rules in the Ocelot switches.
Not all actions are demoed, mostly because of difficulty to automate
this from a single board.
For example, policing. We can set up an iperf3 UDP server and client and
measure throughput at destination. But at least with DSA setups, network
namespacing the individual ports is not possible because all switch
ports are handled by the same DSA master. And we cannot assume that the
target platform (an embedded board) has 2 other non-switch generator
ports, we need to work with the generator ports as switch ports (this is
the reason why mausezahn is used, and not IP traffic like ping). When
somebody has an idea how to test policing, that can be added to this
test.

Instead, change both to use qdiscs. In SW datapath this is the obvious
choice, and now that mlxsw offloads FIFO, this should work on the offloaded

The function busywait() is handy as a safety-latched variant of a while
loop. Many selftests deal specifically with counter values, and busywaiting
on them is likely to be rather common (it is not quite common now, but
busywait() has not been around for very long). To facilitate expressing
simply what is tested, introduce two helpers:
- until_counter_is(), which can be used as a predicate passed to
busywait(), which holds when expression, which is itself passed as an
argument to until_counter_is(), reaches a desired value.
- busywait_for_counter(), which is useful for waiting until a given counter
changes "by" (as opposed to "to") a certain amount.
