Hi,

I did a lot of tests with carp (was not appropriate at all), and ng_one2many

I was able to make two nics appears at one with ng_one2many, but 
after severals days of tests and research, dropped it because it 
caused bad side effects and when I was pulling one nic out, it was 
stopping to transmit/receive for some moment. Also on the switch, 
both nics were registering the same mac address so my cisco was 
sending me warning about it every minute.

If you find a way to make it work that works perfectly, let me know, 
I think a lot of people will benefit from it cause there is a bunch 
of people asking for nic teaming and no real solution...

personnally, I ended up doing the redundancy at layer 3 instead of layer 2.

I used quagga (or zebra) and put one nic in a separate subnet. I then 
used ospf to share routes. basically, my website is on an ip I binded 
to my loopback adapter and there is two gateways (both nics) to the 
rest of the network. It's not a solution I'm proud of because I wish 
I would have succeed to team the nic like I could have done on 
windows or linux, but I didn't find a working solution...

Good luck
