Anything involving multipath-tools settings is a giant nightmare. We
need to get it rifght in the kernel so that multipathing can work
out of the box. And the right place for SCSI-level quirks are the
devlist entries.
Module options for hardware specific behavior are a horrible idea - you
can be connect to different devies, which is a very common setup.
