98 * MegaRAID SAS MFI firmware definitions
99 * =====================================
103 * MFI stands for MegaRAID SAS FW Interface. This is just a moniker for
104 * protocol between the software and firmware. Commands are issued using
105 * "message frames"
109 * FW posts its state in upper 4 bits of outbound_msg_0 register
