The negotiation process may be smarter now, but I know a few years
back setting a router/switch port to full duplex turned off any
negotiation with the connected device and any device that did
not offer to negotiate was assumed to be half duplex by it's partner.
Either that situation has changed or your clients are doing the wrong
thing even though the result is what you want.  Anyway, these days I
try to leave everything on auto unless I know that even with the
latest firmware/drivers it still won't work.
