So I wonder why multiple OEMs decided to use Mellanox for on-board solutions and no one used the QLogic silicon...

Surprise surprise... this is no more than FUD. If you have real numbers to back it up please send. If it was so great, how come more people decided to use the Mellanox solutions? If QLogic was doing so great with their solution, I would guess they would not be selling the IB business...
