Hi Idan,

One minor nit, there is no "secured mode", its the normal sane
mode. The other mode compromises insecurity for performance.

That is very good! Thanks for doing this!
You should note that its mlx5 specific enhancement, which is
an important device, but its not a performance improvement for
RDMA ULPs as it is.

What about mlx4 btw?
