Add the multiple subflows test case for MP_FAIL, to test the MP_FAIL
reset case. Use the test_linkfail value to make 1024KB test files.
Invoke reset_with_fail() to use 'iptables' and 'tc action pedit' rules
to produce the bit flips to trigger the checksum failures on ns2eth2.
Add delays on ns2eth1 to make sure more data can translate on ns2eth2.
The check_invert flag is enabled in reset_with_fail(), so this test
prints out the inverted bytes, instead of the file mismatch errors.
Invoke pedit_action_pkts() to get the numbers of the packets edited
by the tc pedit actions, and print this numbers to the output.

This patch adds a test that has 300 VIPs listening on port 443.
Each VIP:443 will have 80 listening socks by using SO_REUSEPORT.
Thus, it will have 24000 listening socks.
Before removing the port only listening_hash, all socks will be in the
same port 443 bucket and inet_reuseport_add_sock() spends much time to
walk through the bucket. After removing the port only listening_hash
and move all usage to the port+addr lhash2, each bucket in the
ideal case has 80 sk which is much smaller than before.
Here is the test result from a qemu:
Before: listen 24000 socks took 210.210485362 (~210s)
After: listen 24000 socks took 0.207173 (~210ms)

The host interfaces $h1 and $h2 don't have to be switchdev interfaces,
but due to the fact that we pass $tcflags which may have the value of
"skip_sw", we force $h2 to offload a drop rule for dst_ip, something
which it may not be able to do.
The selftest only wants to verify the hit count of this rule as a means
of figuring out whether the packet was received, so remove the $tcflags
for it and let it be done in software.

The 'ping' utility is able to manage two kind of sockets (raw or icmp),
depending on the sysctl ping_group_range. By default, ping_group_range is

Let's replay the ping tests by allowing 'ping' to use the ip icmp socket.

of socket. For ipv6, there are a lot a new failures (the previous patch

the default conform-exceed action is "reclassify", for a reason we don't
really understand.
The point is that hardware can't offload that police action, so not
specifying "conform-exceed" was always wrong, even though the command
used to work in hardware (but not in software) until the kernel started
adding validation for it.
Fix the command used by the selftest by making the policer drop on
exceed, and pass the packet to the next action (goto) on conform.

Since riscv doesn't have a second serial port in its device description,

that these separate threads wind up fighting with the scheduler, and we

A number of mlxsw-specific QoS tests use manual QoS DCB management. As
such, they need to make sure lldpad is not running, because it would
override the configuration the test has applied using other tools. To that
end, these selftests invoke the bail_on_lldpad() helper, which terminates
the selftest if th lldpad is running.
Some of these tests however first install the bash exit trap, which invokes
a cleanup() at the test exit. If bail_on_lldpad() has terminated the script
even before the setup part was run, the cleanup part will be very confused.
Therefore make sure bail_on_lldpad() is invoked before the cleanup is
registered.
While there are still edge cases where the user terminates the script
before the setup was fully done, this takes care of a common situation
where the cleanup would be invoked in an inconsistent state.

It is used in self-testing scripts that exercise MPTCP netlink commands
to precisely validate those operations by examining the dispatched
MPTCP netlink events in response to those commands.

Check userspace PM behavior to ensure ADD_ADDR echoes are only sent when
there is an active userspace daemon. If the daemon is restarting or
hasn't loaded yet, the missing echo will cause the peer to retransmit
the ADD_ADDR - and hopefully the daemon will be ready to receive it at
that later time.

The program uses CLOCK_TAI as default clock since it was added to the
Linux repo. In commit:
| 040806343b ("selftests/net: so_txtime multi-host support")
a help text stating the wrong default clock was added.
This patch fixes the help text.

In emulated environments, the bridge ports enslaved to br1 get a carrier
before changing br1's PVID. This means that by the time the PVID is
changed, br1 is already operational and configured with an IPv6
link-local address.
When the test is run with netdevs registered by mlxsw, changing the PVID
is vetoed, as changing the VID associated with an existing L3 interface
is forbidden. This restriction is similar to the 8021q driver's
restriction of changing the VID of an existing interface.
Fix this by taking br1 down and bringing it back up when it is fully
configured.
With this fix, the test reliably passes on top of both the SW and HW
data paths (emulated or not).

The Felix VSC9959 switch in NXP LS1028A supports the tc-gate action
which enforced time-based access control per stream. A stream as seen by
this switch is identified by {MAC DA, VID}.
We use the standard forwarding selftest topology with 2 host interfaces
and 2 switch interfaces. The host ports must require timestamping non-IP
packets and supporting tc-etf offload, for isochron to work. The
isochron program monitors network sync status (ptp4l, phc2sys) and
deterministically transmits packets to the switch such that the tc-gate
action either (a) always accepts them based on its schedule, or
(b) always drops them.
I tried to keep as much of the logic that isn't specific to the NXP
LS1028A in a new tsn_lib.sh, for future reuse. This covers
synchronization using ptp4l and phc2sys, and isochron.
The cycle-time chosen for this selftest isn't particularly impressive
(and the focus is the functionality of the switch), but I didn't really
know what to do better, considering that it will mostly be run during
debugging sessions, various kernel bloatware would be enabled, like
lockdep, KASAN, etc, and we certainly can't run any races with those on.
I tried to look through the kselftest framework for other real time
applications and didn't really find any, so I'm not sure how better to
prepare the environment in case we want to go for a lower cycle time.
At the moment, the only thing the selftest is ensuring is that dynamic
frequency scaling is disabled on the CPU that isochron runs on. It would
probably be useful to have a blacklist of kernel config options (checked
through zcat /proc/config.gz) and some cyclictest scripts to run
beforehand, but I saw none of those.
