Author: hselasky Date: Mon Aug 29 08:52:53 2016 New Revision: 304999 URL: https://svnweb.freebsd.org/changeset/base/304999 Log: MFC r304629: Don't separate the status stage of the XHCI USB control transfers into its own job because this breaks the simplified QEMU XHCI TRB parser, which expects the complete USB control transfer as a series of back to back TRBs. The old behaviour is kept under #ifdef in case this change breaks enumeration of any USB devices.
