Subject: [PATCH v3 0/2] net/tcp: fix permanent FIN-WAIT-1 state and add packetdrill test

Hi Kuniyuki,

Thank you for the feedback. I've shortened the test duration in v3.

The test is now:
- Moved to tools/testing/selftests/net/packetdrill/
- Reduced from 360+ seconds to under 4 seconds

Please see the v3 series for details.

Best regards,
HaiYang Zhong
