The TODO file says:

What is the speed needed for?

SBP-2 says:
| The target shall issue data transfer requests with a speed equal to
| that specified by the spd field in the ORB.

SBP-3 says:
| The target shall issue data transfer requests with a speed equal to
| that specified by the controlling spd field, whether in the ORB or in
| a node selector in an associated page table.

That driver should not, by default, log into targets on its own node.
