Nonsense, sorry. Haven't spent the appropriate attention before… But since this is a major issue for if_lagg(4) users, I did at least a comperhensive state change test. All if_igb(4) NICs I have available for testing are affecetd, and also if_em(4) with 82574L (Hartwell). Please see the mentioned bug report, where I added all tested NICs. Couldn't remember where I used a i211 (Pearsonville, not Powerville), so this is missing the the latest test. Thanks, -Harry
