Detailed Description

struct mpt2_diag_query - query relevant info associated with diag buffers - generic header - - specifies either TRACE, SNAPSHOT, or EXTENDED - misc flags - specifies flags affecting command processing - product specific information - diag buffer size in bytes - size of extra space appended to end of buffer - unique id associated with this buffer.

The application will send only buffer_type and unique_id. Driver will inspect unique_id first, if valid, fill in all the info. If unique_id is 0x00, the driver will return info specified by Buffer Type.
