scsi: megaraid_sas: mismatch of allocated MFI frame size and length exposed in MFI MPT pass through command
Driver allocated 256 byte MFI frames bytes but while sending MFI frame
(embedded inside chain frame of MPT frame) to firmware, driver sets the
length as 4k. This results in DMA read error messages during boot.
