>Description:

The following causes the kernel to panic

# ifconfig vlan0 create
# ifconfig vlan0 vlan 129 vlanif tlp1
# ifconfig vlan0 64.21.129.1 netmask 0xffffff00
uvm_fault(0xcb1acb04, 0x0, 0, 2) -> e
kernel: page fault trap, code=0
Stopped in pid 333 (ifconfig) at       tlp_filter_setup+0x424: movl    %eax,    0
x8(%edi)
db>

There is no link on the interface at this time. Unsure if this is related to
the problem.

>How-To-Repeat:
# ifconfig vlan0 create
# ifconfig vlan0 vlan 129 vlanif tlp1
# ifconfig vlan0 64.21.129.1 netmask 0xffffff00
