On stable/13 (GENERIC without COMPAT_FREEBSD12): # ifconfig vlan99 create ==> vlanproto: 0x0000 # ifconfig vlan99 vlan 99 vlandev igb0 ==> vlanproto: 802.1q # ifconfig vlan99 destroy # ifconfig vlan99 create vlan 99 vlandev igb0 ==> vlanproto: 802.1q On stable/14 or main (GENERIC without COMPAT_FREEBSD12): # ifconfig vlan99 create ==> vlanproto 0x0000 # ifconfig vlan99 vlan 99 vlandev igb0 ==> vlanproto 0x0000# # ifconfig vlan99 create vlan 99 vlandev igb0 ==> vlanproto: 802.1q I guess that's why the following lines in my /etc/rc.conf no longer work on stable/14 or main (without COMPAT_FREEBSD12): cloned_interfaces="vlan99" ifconfig_vlan99="vlan 99 vlandev igb0" I have to replace the ifconfig line with: ifconfig_vlan99="vlan 99 vlandev igb0 vlanproto 802.1q" It also works if I remove the following lines in sys/net/if_vlan.c: 1110 #ifdef COMPAT_FREEBSD12 1113 #endif 2265 #ifdef COMPAT_FREEBSD12 2268 #endif -- Herbert
