Hello, 

I've never had heard talking about ng_fec, so I've been
looking at the pointers of the previous mails and I find it
very interesting, but there are some things I don't understand
well.

For example, if we aggregate 4 ethernet cards into one
virtual interface (fec), do this mean that the throughput is
4 times the capacity of one ethernet card ?. 

Also, if the pyshical interfaces are connected to different LANs,
how can we think about the virtual iface ? is it as if we were
joining the 4 LANs to make one common link ? is this right ?
