Indicates the administrative link type configuration of
a bridge port for the MST protocol.
pointToPoint -- the port is administratively configured to
be connected to a point-to-point link.
shared -- the port is administratively configured to be
connected to a shared medium.
auto -- the administrative configuration of the port's
link type depends on link duplex of the port.
If the port link is full-duplex, the administrative
link type configuration on this port will be taken
as pointTopoint(1). If the port link is half-duplex,
the administrative link type configuration on this
port will be taken as shared(2).
This configuration of this object only takes effect when the
stpxSpanningTreeType is mst(4) or rapidPvstPlus(5).
stpxMSTPortAdminLinkType is deprecated and replaced
with stpxRSTPPortAdminLinkType.
