Subject: [PATCH net-next 0/4] selftests: Use busywait() in a couple places

From: Petr Machata <petrm@...lanox.com>

Two helper function for active waiting for an event were recently
introduced: busywait() as the active-waiting tool, and until_counter_is()
as a configurable predicate that can be plugged into busywait(). Use these
in tc_common and mlxsw's qos_defprio instead of hand-coding equivalents.

Patches #1 and #2 extend lib.sh facilities to make the transition possible.
Patch #3 converts tc_common, and patch #4 qos_defprio.

Petr Machata (4):
  selftests: forwarding: lib: Add tc_rule_handle_stats_get()
  selftests: forwarding: Convert until_counter_is() to take expression
  selftests: forwarding: tc_common: Convert to use busywait
  selftests: mlxsw: qos_defprio: Use until_counter_is
