Hi Aleksandr, Part of this patch was to introduce a driver-dependent iflib function that would allow drivers to tell iflib whether or not to flap the interface when a vlan is registered or unregistered. I think this could be fixed for em(4) by having it implement that function to either always return false (so iflib doesn't do an init/stop), or maybe have it only do a reset when vlanhwfilter is enabled; I'm going to take a look at doing that.
