Surprise Down error reporting capabilities.
(Available in PCI Express Base Specification Revision 1.1
compliant Cores, only.)
Downstream Port. This bit must be set to 1 if the
component supports the optional capability of detecting
and reporting a Surprise Down error condition.
Upstream Port. For upstream ports and components
that do not support this optional capability, this bit must
be hardwired to 0.
Data Link Layer active reporting capabilities.
(Available in PCI Express Base Specification Revision 1.1
compliant Cores, only.)
Downstream Port: This bit must be set to 1 if the
component supports the optional capability of reporting
the DL_Active state of the Data Link Control and
Management state machine.
Upstream Port: For upstream ports and components that
do not support this optional capability, this bit must be
hardwired to 0.
