[PATCH 01/15] megaraid_sas: mismatch of allocated MFI frame size and length exposed in MFI MPT pass through command

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



 Fix - 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.
