I posted instructions a while ago on how to setup ng_fec along with an 
HP ProCurve switch supporting FastEtherchannel -- the same should also 
apply for Cisco switches. Be warned that newer HP/Cisco gear has dropped 
support for FEC in favour of 802.3ad/LACP...

I haven't experimented with ng_one2many, but my understanding is that it 
only provides a "dumb" balancing/bonding solution.

Presumably we need an ng_bonding or something along those lines would be 
required to achieve parity with what Linux can provide...?
