Yes, I was reading some HP docs yesterday and they implied that they 
were removing FEC on newer switches in favour of using the IEEE 
standards-based methods of trunking.

I wonder how dissimilar FEC and IEEE LACP are from one another? ie. how 
much of the code from ng_fec could be used to implement an ng_lacp...
