I'm not sure how important of a subtlety this is, but the actual
console log after the patch is the following:
i40e 0000:82:00.0: TX driver issue detected, PF reset issued
i40e 0000:82:00.0 eth2: adding 68:05:ca:30:dd:18 vid=0
i40e 0000:82:00.0: TX driver issue detected, PF reset issued
i40e 0000:82:00.0 eth2: adding 68:05:ca:30:dd:18 vid=0
i40e 0000:82:00.0: TX driver issue detected, PF reset issued
Comparing with what I'd pasted in the sourceforge thread earlier,
I see that it does not say "Hung Tx queue etc." any more, though
it still resets.
Not sure if that changed info is significant?
