Various optional features of a link station.
autoActSupp
If present specifies that the link can be activated automatically when
required by a session. A link cannot be automatically activated from
an independent LU session unless it has been started previously.
The link cannot be defined to support CP-CP sessions and to be
auto-activatable because this might cause inconsistent network
behavior.
limitedResource
If present, specifies that this link station is to be deactivated when
there are no sessions using the link. Note that link stations on a non-
switched port cannot be configured as limited resource.
backLvlLenEn
If present, specifies that this link is to a back level LEN End Node.
cpCpSessSupport
If present, specifies that CP-CP sessions are supported by this link
station.
