The busywait timeout value is a millisecond, not a second. So the current setting 2 is meaningless. Let's copy the WAIT_TIMEOUT from forwarding/lib.sh and set a BUSYWAIT_TIMEOUT here.
Signed-off-by: Hangbin Liu liuhangbin@gmail.com --- Not sure if the default WAIT_TIMEOUT 20s is too large. But since we usually don't need to wait for that long. I think it's OK to stay the same value with forwarding/lib.sh. Please tell me if you think we need to set a more proper value.
BTW, This doesn't look like a fix. But also not a feature. So I just post it to net tree. --- tools/testing/selftests/net/lib.sh | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-)
