Merge branch 'tid-read' into hfi1-tid
This is the series for adding TID RDMA read. Kaike put in a lot of
effort into making this more consumable for review so special thanks to
him.
Allocating resources and tracing are separated out followed by patches
which build up the read request. Then we have the patches to receive
incoming TID RDMA read requests and handle integration with the RC
protocol.
See the cover letter of the original posting for more of a detailed
overview of TID.
