## version messages

### 1st test 
root at JIKE-GATEWAY ~>ip lin set dev eth0 group 100
root at JIKE-GATEWAY ~>ip lin set dev eth1 group 200
root at JIKE-GATEWAY ~>iptables -I FORWARD -m devgroup --src-group 100 -m devgroup
--dst-group 200 -j ACCEPT

root at JIKE-GATEWAY ~>iptables-save |grep devgroup
-A FORWARD -m devgroup --src-group 0x64 -m devgroup --dst-group 0x0/0x0 -j
ACCEPT

root at JIKE-GATEWAY ~>iptables -nvL |grep src-group
    0     0 ACCEPT     all  --  *      *       0.0.0.0/0            0.0.0.0/0  
         src-group 0x64 dst-group 0x0/0x0

### dest-group 0x0/0x0 was not just as my set


### 2nd test
root at JIKE-GATEWAY ~>ip lin set dev eth3 group 300
root at JIKE-GATEWAY ~>ip lin set dev eth4 group 400
root at JIKE-GATEWAY ~>iptables -I FORWARD -m devgroup --src-group 300 --dst-group
400 -j ACCEPT


root at JIKE-GATEWAY ~>iptables-save |grep devgroup
-A FORWARD -m devgroup --src-group 0x12c --dst-group 0x12c -j ACCEPT

root at JIKE-GATEWAY ~>iptables -nvL |grep src-group
    0     0 ACCEPT     all  --  *      *       0.0.0.0/0            0.0.0.0/0  
         src-group 0x12c dst-group 0x12c

## again ,dst-group was wrong

i am not sure wether this is a bug? or i cann't use devgroup like this, or
something else?
