This RFC introduces an ability to user space application to work with contiguous pages when ibv_reg_mr is used. This ability achieved by asking the provider as part of ibv_reg_mr to allocate from the kernel such a memory in a transparent way to the application. The idea is to pass NULL as part of ibv_reg_mr and turn on an access flag bit asking for that. Patches: #1 - Add the above support as part of ibv_reg_mr. #2 - Example usage as part of ibv_rc_pingpong.
