7700476f31 selftests: mlxsw: Fix local variable declarations in DSCP tests
These two tests have some problems in the global scope pollution and on
contrary, contain unnecessary local declarations. Fix them.

f3b05bb819 selftests: mlxsw: Update ping limits
The current ping intervals are too short for running mirroring tests in
simulator. This leads to ping sending a follow-up ping before the reply
arrives, thus sending more than the requested 10 ICMP requests. This
traffic is seen at the counters, and causes spurious failures.

Bump interval and timeout numbers 5x in mirroring tests to address the
spurious failures.

b6a4fd6800 selftests: forwarding: Make ping timeout configurable
The current timeout (2 seconds) proved to be too low for some (emulated)
systems where we run the tests.

Make the timeout configurable and default to 5 seconds.

cf60869814 selftests: forwarding: Move DSCP capture to lib.sh
dscp_capture_install() and dscp_capture_uninstall() are going to be
useful for a test added by a following patch, move them therefore to
lib.sh together with related helpers.

While doing so, change the rule preference from mere DSCP value to
DSCP+100 in order to support adding captures of packets with DSCP of 0.

989133bf7f selftests: forwarding: Move lldpad waiting to lib.sh
The function lldpad_wait() will be useful for a test added by a
following patch. Likewise would the "sleep 5" with its extensive
comment.

Therefore move lldpad_wait() to lib.sh in order to allow reuse. Rename
it to lldpad_app_wait_set() to recognize that what this is intended to
wait on are the pending APP sets.

For the sleeping, add a function lldpad_app_wait_del(). That will serve
to hold the related explanatory comment (which edit for clarity), and as
a token in the caller to identify the sites where this sort of waiting
takes place. That will serve when/if a better way to handle this
business is found.

eef6ab8b7d selftests: mlxsw: qos_dscp_bridge: Fix
There are two problems in this test case:

- When indexing in bash associative array, the subscript is interpreted as
  string, not as a variable name to be expanded.

- The keys stored to t0s and t1s are not DSCP values, but priority +
  base (i.e. the logical DSCP value, not the full bitfield value).

In combination these two bugs conspire to make the test just work,
except it doesn't really test anything and always passes.

Fix the above two problems in obvious manner.

d159261f36 selftests: mlxsw: Add test for trust-DSCP
Add a test that exercises the new code. Send DSCP-tagged packets, and
observe how they are prioritized in the switch and the DSCP is updated
on egress again.
