This is a performance improvement patch series. It adds an adaptive PIO component where under certain conditions small messages will be sent via PIO instead of SDMA. This series also includes a change to the progress mechanism and its interaction with rdmavt enabling a driver hint as to if the progress should be kicked or the send just queued. Series applies on the posted "Code cleanups, bug fixes, and perf improvements" patch. It can also be seen in context at https://github.com/ddalessa/kernel/tree/for-4.6. --- Dennis Dalessandro (1): staging/rdma/hfi1: Remove header memcpy from sdma send path.
