HNSDV(7)                 HNS Direct Verbs Manual                 HNSDV(7)

NAME         top

       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         top

       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.
