The variable is used by log_test() to check if the test case completely successfully or not. In case it is not initialized at the start of a test case, it is possible for the test case to fail despite not encountering any errors. Example: ``` ... TEST: Trap group statistics [ OK ] TEST: Trap policer [FAIL] Policer drop counter was not incremented TEST: Trap policer binding [FAIL] Policer drop counter was not incremented ``` Failure of trap_policer_test() caused trap_policer_bind_test() to fail as well.

2020-02-27selftests: devlink_trap_l3_drops: Avoid race conditionIdo Schimmel-8/+3
The test checks that packets are trapped when they should egress a router interface (RIF) that has become disabled. This is a temporary state in a RIF's deletion sequence. Currently, the test deletes the RIF by flushing all the IP addresses configured on the associated netdev (br0). However, this is racy, as this also flushes all the routes pointing to the netdev and if the routes are deleted from the device before the RIF is disabled, then no packets will try to egress the disabled RIF and the trap will not be triggered. Instead, trigger the deletion of the RIF by unlinking the mlxsw port from the bridge that is backing the RIF. Unlike before, this will not cause the kernel to delete the routes pointing to the bridge. Note that due to current mlxsw locking scheme the RIF is always deleted first, but this is going to change.
