Hi, This patch series aims to allow the lvstest driver to work with xHCI 1.1 hosts. In xHCI 1.1 a downstream port might not automatically enter compliance mode upon LFPS timeout; instead the port must be explicitly enabled to allow this transition. This is needed to pass the Link Layer test case TD.7.34 in which the test operator is prompted to put the port in compliance mode before proceeding with the test. This requires adding support to the xhci hub driver to accept a SET_FEATURE(PORT_LINK_STATE) request for the compliance state and a new 'enable_compliance' sysfs entry to lvstest which invokes it.
