Right now the best way to find out about the userspace verbs API is to
look at the libibverbs source.  The include file infiniband/verbs.h
and the code in the examples directory are probably the best places to
get started.

The current code implements all the main verbs likely to be used by
userspace applications.  There are no functions that I can think of
added beyond what's in VAPI.
