(Andrew Rybchenko) 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?
