already did:
change uclinux4skyeye's skyeyene2k.c: 
        * skyeyene2k.c version 0.2
        * support that skyeye reads mac addr from skyeye.conf
        * modify skyeyene2k.c::sene2k_open :add code to  get mac addr from PADR[0-5]
        * modify skyeyene2k.c::sene2k_init :delete code to set mac addr manually
chage skyeye::skyeye-ne2k.c::nic_reset
        * put mac addr from skyeye.conf to PADR[0-5]
chage skyeye::skyeye_net_vnet.c::vnetif_init
        * set flag=flag=IFF_UP|IFF_RUNNING|IFF_BROADCAST and ioctl to vnet device file

--------------------------------------
result:
skyeye support vnet
but seems have some bugs
--------------------------------------
need to do:
more test
vnet support hostip <-> guestip

-------------------------
already did:
change skyeye to support vnet or tuntap at the sametime
add&changeed files in projects/skyeye
skyeye_net.c skyeye_net_tuntap.c skyeye_net_vnet.c
skyeye_config.h skyeye_options.c ....

-------------------------
result:

but when use vnet, vnet's mac addr mispatch (seems lwiponucosii and uclinux set the mac addr manually, but skyeye set mac addr at the skyeye_init, ) 
 
---------------------------
need to do:
test skyeye for vnet

-------------------------
already did:

build testvnet4.c : testvnet c  client write data to server , testvnet s server read data from client
build testvnet5.c : compared to testvnet4, testvnet5 test the select function, to test vnet_chr_poll 
ioctl process can support set/get  mac addr,ifflag guestif flag must be (UP|RUNNING|...)can recv packet
add function:    
vnet_guestif_poll/read/write/recv  vnet_hub_recv ...
nut has type:VNET_GUESTIF_NUT VNET_HOSTIF_NUT VNET_HUB_NUT

--------------------------
result:
testvnet4.c passed: send a packet from client to server
testvnet5.c passed: server select and read, clinet write

clean bugs

??? means i don't understand
