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  implementa‐
       tion.   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 opera‐
       tions, 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  inter‐
       face.
