The hardware supported by mfi(4) and mrsas(4) use the same dcmd's. mfiutil(8) in theory could run on controlled attached to mrsas(4). It can't since mrsas(4) doesn't have support for the FreeBSD mfi(4) ioctl. Porting the ioctl from mfi(4) to mrsas(4) would be the first step in making mrsasutil(8) which is an additional name for mfiutil(8) but opens /dev/mrsasX instead of /dev/mfiX PR: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=265794 Reviewed by: jhb Differential revision: https://reviews.freebsd.org/D36342 Tested by: Dan Mahoney <freebsd@gushi.org>
