[VLAN] shell hangs caused by 'vconfig rem'

[石洋]

Hi guys,
 
When I work on sbc8560 board, I met a problem related to vlan.
 
Steps to reproduce:
# modprobe 8021q
# vconfig add eth1 5
Added VLAN with VID == 5to IF -:eth1:-
# ifconfig eth1.5 192.168.118.49 netmask 255.255.255.192 up
Then unplug the ethernet cable, then link is down.
# vconfig rem eth1.5
Shell prompt hangs there
If the cable plugged, it gets back and completes VLAN removing.
 
I am using linux-2.6.14 kernel, and I enable ipv6 and ip_tables module, but my network enviorment is ipv4.
 
I saw there are several discussions about a similiar case in mailing list. The latest disscussion is http://ns2.lanforge.com/pipermail/vlan/2006-October/000905.html
 
If this is the same bug or not? Could give me some suggestion?
 
Thanks
