[ofw] [PATCH 4/9] uvp/interface: add support for reporting QP context in WCs

Wed Jun 25 16:52:40 PDT 2008
Extend the uvp_interface to include support for reporting the QP context in
work completions. The required changes are to allow specifying a qp_context
in the pre_create_qp() IOCTL call, and reporting the qp_context through the
work completion structure.
Having the QP context is particularly useful when SRQs are used.
