Drivers may need to do some work once an address handle has been
created. Add a driver function for this purpose.

Converge the ibport data structures of qib and hfi1 into a common ib
port structure. Also provides a place to keep track of these ports
in case rdmavt needs it. Along with this goes an attach and detach
function for drivers to use to notify rdmavt of the ports.

Original patch is from Kamal Heib <kamalh@mellanox.com>. It has
been split into three separate patches. This one for rdmavt,
a follow on for qib, and one for hfi1.
Create datastructure for address handle and implement the
create/destroy/modify/query of address handle for rdmavt.

Drivers will need a set of flags to dictate behavior to rdmavt. This patch
adds a placeholder and a spot for it to live, as well as a few flags
that will be used.

Follow hfi1's example for printing information about the driver and
incorporate into rdmavt. This requires two new functions to be
provided by the driver, one to get_card_name and one to get_pci_dev.

Drivers are going to need to provide multiple functions for rdmavt to
call in to. We already have one, so go ahead and push this into a
data structure designated for driver supplied functions.

This patch adds the MR datastructures based on hfi1 into rvt. For now the
data structures are defined in include/rdma/rdma_vt.h but once all MR
functionality has been moved from the drivers into rvt these should move to
rdmavt/mr.h

The pkey table will reside in the rvt structure but it will be modified
only when the driver requests then rvt will simply read the value to return

to rvt_driver_params. This means drivers will fill this in and pass to the

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.
