mfiutil(8) in theory can work on devices attached to mrsas(4) but mrsas(4) is missing the FreeBSD mfi(4) ioctl support. Once that support is added to mrsas(4) then mrsasutil(8) can manage mrsas(4) attached devices. So this commit depends on that. When mrsasutil(8) is run it automatically opens /dev/mrsas0 instead of /dev/mfi0. Add -D <device> and -t <type> flag to optionally specify mrsas or mfi to work with the existing -u <unit>. Device is the device node with or without /dev/ PR: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=265794 Differential Revision: https://reviews.freebsd.org/D36343 Tested by: Dan Mahoney <freebsd@gushi.org> Reviewed by: jhb
