sata_mv ncq Introduce per-tag SG tables In preparation for supporting NCQ, we must allocate separate SG tables for each command tag, rather than just a single table per port as before. Gen-I hardware cannot do NCQ, though, so we still allocate just a single table for that, but populate it in all 32 slots to avoid special-cases elsewhere in hotter paths of the code.
