I noticed that the Linux MegaRAID driver for SAS based RAID controllers has
the same aforementioned module parameter. Despite the potential performance
drawbacks, I suspect it would be useful with the Broadcom MPI3 Storage
Controller Driver too, to respect the default IRQ affinity.
Please let me know your thoughts.
