This test lacks a topology diagram, making the setup not obvious.

The ethtool dump includes the lanes parameter only when the port is up.
Therefore, the ethtool_lanes.sh test waits for ports to come before testing
the lanes parameter.
In some cases, the test considers the port as up, but the lanes parameter
is not yet dumped although assumed to be, resulting in ethtool_lanes.sh
test failure.
To avoid that, ensure that the lanes parameter is indeed dumped by waiting
for it explicitly, before preforming the test cases.

The tests use the constant TC_HIT_TIMEOUT when waiting on the counter
values. However it does not include tc_common.sh where the counter is
specified. The test has been robust in our testing, which means the counter
is bumped quickly enough that the updated value is available already on the
first iteration. Nevertheless it's not correct. Include tc_common.sh as
appropriate.

Some log_test calls are done in a loop, and lead to the same log output.
This might prove tricky to deduplicate for automated tools. Instead, roll
the unique information from log_info to log_test, and drop the log_info.
This also leads to more compact and clearer output.
This change prompts rewording the messages so that they are not excessively
long.
Some check_err messages do not indicate what the issue actually is, so
reword them to say it's a "ping with", like is the case in some other
instances in this test.

When rx-pktsNtoM reports a range that involves very low-valued range, such
as 0-64, the calculated length of the packet will be -4, because FCS is
subtracted from the value. mausezahn then confuses the value for an option
and bails out. As a result, the test dumps many mausezahn error messages.
Instead, cap the value at 0. mausezahn will use an appropriate minimum
packet length.

Bodies of busywait() and slowwait() functions are almost identical. Extract
the common code into a helper, loopy_wait, and convert busywait() and
slowwait() into trivial wrappers.
Moreover, the fact that slowwait() uses seconds for units is really not
intuitive, and the comment does not help much. Instead make the unit part
of the name of the argument to further clarify what units are expected.

This doesn't matter for the CLI but when writing YNL based tests
having to deal with either list or None is annoying. Limit the
None conversion to non-dump ops:

The commit fc8b2a619469
("net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation")
adds check of potential number of UDP segments vs
UDP_MAX_SEGMENTS in linux/virtio_net.h.
After this change certification test of USO guest-to-guest
transmit on Windows driver for virtio-net device fails,
for example with packet size of ~64K and mss of 536 bytes.
In general the USO should not be more restrictive than TSO.
Indeed, in case of unreasonably small mss a lot of segments
can cause queue overflow and packet loss on the destination.
Limit of 128 segments is good for any practical purpose,
with minimal meaningful mss of 536 the maximal UDP packet will
be divided to ~120 segments.
The number of segments for UDP packets is validated vs
UDP_MAX_SEGMENTS also in udp.c (v4,v6), this does not affect
quest-to-guest path but does affect packets sent to host, for
example.
It is important to mention that UDP_MAX_SEGMENTS is kernel-only
define and not available to user mode socket applications.
In order to request MSS smaller than MTU the applications
just uses setsockopt with SOL_UDP and UDP_SEGMENT and there is
no limitations on socket API level.

.. so this can start re-using existing lib.sh infra in next patches.
Several of these scripts will not work, e.g. because they assume
rp_filter is disabled, or reliance on a particular version/flavor
of "netcat" tool.
Add config settings for them.
nft_trans_stress.sh script is removed, it also exists in the nftables
userspace selftests. I do not see a reason to keep two versions in
different repositories/projects.
The settings file is removed for now:
It was used to increase the timeout to avoid slow scripts from getting
zapped by the 45s timeout, but some of the slow scripts can be sped up.
Re-add it later for scripts that cannot be sped up easily.
Update MAINTAINERS to reflect that future updates to netfilter
scripts should go through netfilter-devel@.

We have two printk tests reading trace_pipe in non blocking way,
with the very same code. Moving that in new read_trace_pipe_iter
function.
Current read_trace_pipe is used from samples/bpf and needs to
do blocking read and printf of the trace_pipe data, using new
read_trace_pipe_iter to implement that.
Both printk tests do early checks for the number of found messages
and can bail earlier, but I did not find any speed difference w/o
that condition, so I did not complicate the change more for that.
Some of the samples/bpf programs use read_trace_pipe function,
so I kept that interface untouched. I did not see any issues with
affected samples/bpf programs other than there's slight change in
read_trace_pipe output. The current code uses puts that adds new
line after the printed string, so we would occasionally see extra
new line. With this patch we read output per lines, so there's no
need to use puts and we can use just printf instead without extra
new line.

Move more functionality into dsos.c generally from machine.c, renaming
functions to match their new usage.
The find function is made to always "get" before returning a dso.
Reduce the scope of locks in vdso to match the locking paradigm.

Move functions from machine and build-id to dsos. Pass 'struct dsos'
rather than internal state.
Rename some functions to better represent which data structure they
operate on.
