ifupdown: fix issue for configuring loopback interface
The patch inet-6-.defn-fix-inverted-checks-for-loopback.patch introduced
an issue that ifup/ifdown can not configure loopback interface:
$ cat /etc/network/interfaces
auto lo
iface lo inet loopback
$ ifconfig -s
Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg
eth0 1500 0 1 0 0 0 74 0 0 0 BMRU
lo 65536 0 2 0 0 0 2 0 0 0 LRU
$ ifdown lo
$ ifconfig -s
Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg
eth0 1500 0 1 0 0 0 74 0 0 0 BMRU
lo 65536 0 2 0 0 0 2 0 0 0 LRU
The original patch is for 0.7.x and the change is not needed for 0.8.x.
Update the patch to make the ifup/ifdown can configure lo interface:
$ ifconfig -s
Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg
eth0 1500 0 0 0 0 0 77 0 0 0 BMRU
lo 65536 0 2 0 0 0 2 0 0 0 LRU
$ ifdown lo
$ ifconfig -s
Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg
eth0 1500 0 0 0 0 0 80 0 0 0 BMRU
$ ifup lo
$ ifconfig -s
Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg
eth0 1500 0 0 0 0 0 81 0 0 0 BMRU
