[ofa-general] MLX HCA: CQ request notification for multiple completions not implemented?

[Yicheng Jia]

Hi Folks,

I'm trying to use CQ Event notification for multiple completions (ARM_N) 
according to Mellanox Lx III user manual for scatter/gathering RDMA. 
However I couldn't find it in current MLX driver. It seems to me that only 
ARM_NEXT and ARM_SOLICIT are implemented. So if there are multiple work 
requests, I have to use "poll_cq" to synchronously wait until all the 
requests are done, is it correct? Is there a way to do asynchronous 
multiple send by subscribing for a ARM_N event?

Thanks!
Yicheng
