Hi Doug, Yishay, I need to translate sgid_index to sgid in the library to check for loopback. While invoking ibv_query_gid does the job, it seems to me somewhat inadequate that a provider library invokes an ibv function and not an ibv_cmd function. What are your thoughts on this? I would have invoked the ibv_cmd_query_gid, but there is no such function because ibv_query_gid does not require the kernel. However there's an old *declaration* of the ibv_cmd_query_gid. Perhaps I will define the function in a similar way to ibv_query_gid?!
