64 * We need to use the same values as the mfi driver until MegaCli adds
65 * support for this (mrsas) driver:
66 *    M is for MegaRAID. (This is typically the vendor or product initial)
67 *    1 arbitrary. (This may be used to segment kinds of commands.
68 *    (1-9 status, 10-20 policy, etc.)
69 *    struct mrsas_iocpacket (sizeof() this parameter will be used.)
70 * These three values are encoded into a somewhat unique, 32-bit value.
