No I wouldn't expect it to, nor did I state anything about defaulting to
half. There is no purpose for half-duplex in GIGE, even the few GIGE hubs
I've seen are buffered and user congestion control to allow full duplex
operation. The possibility of half-duplex mode just adds unneeded cruft
and additional failure modes.
