New Revision: 304994
URL: https://svnweb.freebsd.org/changeset/base/304994
Log:
MFC r304597:
Fix for invalid use of bits in input context. Basically split
configuring of EP0 and non-EP0 into xhci_cmd_evaluate_ctx() and
xhci_cmd_configure_ep() respectivly. This resolves some errors when
using XHCI under QEMU and gets is more in line with the XHCI
specification.
