Hi All,
 
I'm having a problem on FreeBSD 6.3 and 7.0 with VLAN management.
After loading my 10GigE driver I'm creating a vlan interface:
 
/sbin/ifconfig vlan3653 create
/sbin/ifconfig vlan3653 vlan 3653 vlandev mynic0
 
Then I'm unloading the driver and everything is fine, the driver interface
remains with a NULL parent.
 
Problem is when I assign an IP to the vlan interface.
In that case, unloading the driver results in hanging the host.
 
Does it sound familiar to anybody?
 
Thanks,
Yony
