Public bug reported:
In this test, it uses ret to store the return value of each test.
However, this value will be reset to 0 in the beginning of each test.
In the end of this test, it will judge PASS/FAIL base on this value.
Thus this will cause false-negative in some cases.
Below is an example for the test on Bionic OEM-OSP1, test "ip6erspan",
"erspan", "ip6gretap" failed with return value 255, but the return value will
soon be overridden with 0 if following test passed without any issue (I made
the test to print === RET $ret === line for debugging purpose):
PASS: policy routing
=== RET 0 ===
PASS: route get
=== RET 0 ===
PASS: preferred_lft addresses have expired
=== RET 0 ===
PASS: tc htb hierarchy
=== RET 0 ===
PASS: gre tunnel endpoint
=== RET 0 ===
PASS: gretap
