ib_srp. 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.
