* comp_vector, a number in the range 0..n-1 specifying the
MSI-X completion vector. Some HCA's allocate multiple (n)
MSI-X vectors per HCA port. If the IRQ affinity masks of
these interrupts have been configured such that each MSI-X
interrupt is handled by a different CPU then the comp_vector
parameter can be used to spread the SRP completion workload
over multiple CPU's.
