My understanding is that NWay is done at the PHY level.  The internal
PHY on the 2114x (at least low values of x) doesn't do NWay.

You can do a software FSM to send a packet figure out if what you send
comes back or not, at full-duplex or 100mbit, but that's not the same
as out-of-band signalling between the two PHY chips.

Please let me know if I'm mistaken. There are some people at Cisco
who'd like to know too :)
