I run an overnight test with v4.12 just to make sure it really fixed the issue. It happened sometimes, but way less frequencies. We may need to test it longer for "good" cases since the patch may not be only one. Anyway, the current status is:
v4.12-rc1 with i40e 2.1.14 - bad (3 out of 3)
v4.12 with i40e 2.1.14 - relatively good (5 out of 68)

The next test would be with v4.12-rc4.
