Hi Thomas, Shahafs,

I guess there was a performance issue on Mellanox with this patch, I assume it
is still valid, since this version only has some cosmetic change, but can you
please confirm?

And what is the next step, can you guys provide some info to Pavan to solve the
issue, or perhaps even better a fix?
