Specifying a value that exceeds cmd_sg_entries is only safe with partial memory descriptor list support enabled (allow_ext_sg=1). + * 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.
