Patches to add LACP >negotiation (FEC is obsolete) are welcome though :) Oups :) Forgot to mention I was looking for switch redundancy also... So each nics were plugged into 2 separate switches so I was not able to configure the switch as trunk or etherchannel... On windows, I am able to team the nics on two different switches without problem with the hp or Intel teaming software, I guess only one nic works at the same time and register it's mac address in the switch tcam... For the original question, it should work with ng_one2Many :)
