| # NAME |
| |
| efadv - Direct verbs for efa devices |
| |
| This provides low level access to efa 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. For some |
| applications optimizing performance is more important than portability. |
| |
| The efa direct verbs API is intended for such applications. |
| It exposes efa specific low level operations, allowing the application |
| to bypass the libibverbs API. |
| |
| The direct include of efadv.h together with linkage to efa library will |
| allow usage of this new interface. |
