New Revision: 305000
URL: https://svnweb.freebsd.org/changeset/base/305000
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.
