Analyze and fix the following issue in the Linux kernel code: selftests: fib_tests: Count all trace point invocations
Problem Details: The tests rely on the IPv{4,6} FIB trace points being triggered once for each forwarded packet. If receive processing is deferred to the ksoftirqd task these invocations will not be counted and the tests will fail. Fix by specifying the '-a' flag to avoid perf from filtering on the mausezahn task. Bef...

Problem Details: The test relies on the fib:fib_table_lookup trace point being triggered once for each forwarded packet.

Fix by explicitly disabling RP filter. ...
