NAME

       hnsdv - Direct verbs for hns devices

       This  provides  low  level  access  to  hns  devices to perform direct operations, without
       general branching performed by libibverbs.

DESCRIPTION

       The libibverbs API is an abstract one.  It is agnostic to any underlying provider specific
       implementation.  While this abstraction has the advantage of user applications portability
       it has a performance penalty.  Besides, some provider specific features that are  directly
       facing  users  are  not available through libibverbs.  For some applications these demands
       are more important than portability.

       The hns direct verbs API is intended for such applications.  It exposes hns  specific  low
       level  operations,  allowing  the application to bypass the libibverbs API and enable some
       hns specific features.

       The direct include of hnsdv.h together with linkage to hns library  will  allow  usage  of
       this new interface.
