GigE is PtP at the physical-layer by the IEEE 802.3ad specification.
It's just not possible to have a dumb, GigE hub. You have to have a
switch that can be told to L2-forward everything to one or more ports
(e.g. through a port-mirroring feature, or by disabling MAC
learning).
Also, though probably not terribly relevant, various switches have
various bugs/malfeatures that cause them to consume certain kinds of
frames rather than forward them (e.g. consuming all or certain kinds
of ISO frames).
