* IB/rdmavt: Add pkey supportDennis Dalessandro2016-03-10
| | | | | | | | | | | | | Add pkey table in rdi per port data structure. Also bring in related pkey functions. Drivers will still be responsible for allocating and maintaining the pkey table. However they need to tell rdmavt where to find the pkey table. We can not move the pkey table up into rdmavt because drivers need to manipulate this long before registering with it.

* IB/rdmavt: Break rdma_vt main include header file upDennis Dalessandro2016-03-10
| | | | | | | | | | | | | | Until all functionality is moved over to rdmavt drivers still need to access a number of fields in data structures that are predominantly meant to be used by rdmavt. Once these rdmavt_<ibta_object>.h header files are no longer being touched by drivers their content should be moved to rdmavt/<ibta_object>.h. While here move a couple #defines over to more general IB verbs header files because they fit better.

* IB/rdmavt: Create module framework and handle driver registrationDennis Dalessandro2016-03-10
This patch introduces the basics for a new module called rdma_vt. This new driver is a software implementation of the InfiniBand verbs and aims to replace the multiple implementations that exist and duplicate each others' code. While the call to actually register the device with the IB core happens in rdma_vt, most of the work is still done in the drivers themselves. This will be changing in a follow on patch this is just laying the groundwork for this infrastructure.
