2017-04-28IB/rdmavt/hfi1/qib: Use the MGID and MLID for multicast addressingMichael J. Ruhl1-17/+44
The Infiniband spec defines "A multicast address is defined by a MGID and a MLID" (section 10.5). The current code only uses the MGID for identifying multicast groups. Update the driver to be compliant with this definition.

2016-12-11IB/hfi1: Replace qp->refcount release code with standard driver wrapperSebastian Sanchez1-3/+2
Some parts of the code don't use the standard release wrapper rvt_put_qp() for decrementing and testing the refcount to then try to use a resource. Replace this code with the standard driver wrapper.

2016-03-11IB/rdmavt: Clean up comments and add more documentationDennis Dalessandro1-3/+31
Add, remove, and otherwise clean up existing comments that are leftover from the initial code postings of rdmavt. Many of the comments were added to provide an idea on the direction we were thinking of going. Now that the design is solidified make a pass over and clean everything up. Also add details where lacking. Ensure all non static functions have nano comments.
