在昨天基础上修正zerg VenderID & DeviceID , 显然内核无法辨认。
修正内核代码中设备识别ne2k_pci_chipsets、pci_clone_list、ne2k_pci_tbl中增加一种zerg VenderID & DeviceID 相关n2k 兼容设备，make && copy kenrnel to grub, restart:

可以工作，一乐。
另外，现在的启动脚本比较管用，备忘如下：
ON:
qemu -M pc -m 1024 -hda ~/pok/imgs/qlnx/lnx.img \
-k en-us \
-net nic,vlan=0 -net tap,vlan=0,ifname=tap0,script=no \
-net nic,model=zerg,vlan=1 -net tap,vlan=1,ifname=tap1,script=no \
-localtime -boot c &
NET-ON:
openvpn --mktun --dev tap0
openvpn --mktun --dev tap1
ifconfig tap0 hw ether 00:e0:fc:00:00:01
ifconfig tap0 172.16.0.1/24
ifconfig tap0 up
ifconfig tap1 hw ether 00:e0:fc:00:01:01
ifconfig tap1 172.16.1.1/24
ifconfig tap1 up
NET-OFF:
ifconfig tap0 down
ifconfig tap1 down
openvpn --rmtun --dev tap0
openvpn --rmtun --dev tap1
