 		streams can be returned to the available secure streams pool by

+Description:
+		(RO) When a host-bridge has root ports that support PCIe IDE
+		(link encryption and integrity protection) there may be a
+		limited number of streams that can be used for establishing new
+		secure links. This attribute decrements upon secure link setup,
+		and increments upon secure link teardown. The in-use stream
+		count is determined by counting stream symlinks.
