intel nic (ixgbe driver) and vlan interfaces

[6bone%6bone.informatik.uni-leipzig.de@localhost]

Hello,

I use an Intel 10GbE card with ixgbe driver. My configuration is as 
follows:

cat ifconfig.ixg0
up

cat ifconfig.vlan103
create
vlan 103 vlanif ixg0 up


The following settings in rc.conf work without problems:

cat /etc/rc.conf
...
auto_ifconfig=NO
net_interfaces="vlan103 ixg0"


With the following configuration vlan interface vlan103 does not work.

cat /etc/rc.conf
...
auto_ifconfig=NO
net_interfaces="ixg0 vlan103"


You can see the problem only after a reboot. Both interfaces are 
generated, both interfaces are up. tcpdump shows incoming packets on the 
interface ixg0. tcpdump shows tagged packets (vlan 103) on the interface 
ixg0. tcpdump shows no packets on the interface vlan103. 'ifconfig -v 
vlan103' shows 0 packets received.

I tried to reproduce the behavior with a 1GB intel NIC. There, the two 
interfaces works indipendent from the order of their creation.

Is there a regulation in which order the interfaces must be generated?

Uwe
