An important update - I have root caused this. Turns out its kinda interesting. The reason there is a problem is due to the stacked pseudo devices, since the vlan device is on lagg, and not directly on em, the em driver is not getting the "event" of the vlan attachment, and thus the vlan hw filter routine is never run, that routine sets a CRITICAL bit in the control register which differentiates between ISL and 802 tags... and thus our failure :( The question now is what to do about this, I am thinking about this now....
