Subject: [PATCH net-next 13/14] selftests: forwarding: lib: Allow reading TC rule byte counters

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

The function tc_rule_stats_get() fetches a packet counter of a given TC
rule. Extend it to support byte counters as well by adding an optional
argument with selector.
