Hi!

I have in rc.conf:
=====================================================================================
vlans_igb0="vlan77 vlan86 vlan87"
create_args_vlan87="vlan 87"
create_args_vlan86="vlan 86"
create_args_vlan77="vlan 77"
ifconfig_vlan87="inet 185.44.68.92 netmask 255.255.252.0 mtu 1500 down up"
ifconfig_vlan87_alias0="link 00:aa:fa:dd:44:55"
ifconfig_vlan86="DHCP mtu 1500"
ifconfig_vlan86_alias0="link 00:ff:fa:dd:44:55"
ifconfig_vlan77="inet 192.168.0.254 netmask 255.255.255.0"
ifconfig_vlan77_alias0="link 00:0f:43:48:67:fe"
ifconfig_vlan77_ipv6="inet6 2001:470:2345:555::1/64 prefixlen 64 auto_linklocal"
ifconfig_igb0="-lro -tso -vlanhwtso mtu 9000 down up"
=====================================================================================

There is 4 different MAC addresses.
System is unavailable after boot until: ifconfig igb0 promisc down up

FreeBSD 13 build from fresh sources.


Is this a bug or this is normal?
