Conrad Meyer 937a702523 NTB: Remap MSI-X messages over available slots ... Remap MSI-X messages over available slots rather than falling back to legacy INTx when fewer MSI-X slots are available than were requested. N.B. the Linux driver does *not* do this. To aid in testing, a tunable 'hw.ntb.force_remap_mode' has been added. It defaults to off (0). When the tunable is enabled and sufficient slots were available, the driver restricts the number of slots by one and remaps the MSI-X messages over the remaining slots. In case this is actually not okay (as I don't yet have access to this hardware to test), a tunable 'hw.ntb.prefer_intx_to_remap' has been added. It defaults to off (0). When the tunable is enabled and fewer slots are available than requested, fall back to legacy INTx mode rather than attempting to remap MSI-X messages.
