Testing by removing vlan hardware filter acceleration (-vlanhwfilter) seems avoiding this problem: # ifconfig igb2.2100 create vlan 2100 vlandev igb2 # dmesg | grep igb2.2100 igb2.2100: link state changed to DOWN igb2.2100: link state changed to UP # ifconfig igb2 -vlanhwfilter # ifconfig igb2.2200 create vlan 2200 vlandev igb2 # dmesg | grep igb2.2200 Could you test this too ? I've filled a PR meanwhile: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=240818 Thanks for the report!
