344 For copper-based boards, the keywords interact as follows:
346 - The default operation is auto-negotiate.  The board advertises all
348   common speed and duplex mode IF the link partner is set to auto-negotiate.
350 - If Speed = 1000, limited auto-negotiation is enabled and only 1000 Mbps
351   is advertised (The 1000BaseT spec requires auto-negotiation.)
353 - If Speed = 10 or 100, then both Speed and Duplex should be set.  Auto-
354   negotiation is disabled, and the AutoNeg parameter is ignored.  Partner
