# This is a simple wrapper for running the MegaCLI tool for Linux.  It assumes
# that the MegaCLI binary has been installed in /compat/linux/usr/sbin/MegaCli.
# The binary must also have been branded appropriately, and the COMPAT_LINUX,
# LINPROCFS, and LINSYSFS options must be enabled.  It is best to enable the
# COMPAT_LINUX option and compile the mfi driver into the kernel, instead of
# loading it as a module, to ensure that all of the required driver bits are
# enabled.
