Revision b1df99d9434edf3fc26f9e36ee6a443e3611e829 authored by Sumant Patro on 03 October 2006, 19:40:47 UTC, committed by James Bottomley on 04 October 2006, 17:48:17 UTC 
[SCSI] megaraid_sas: frame count optimization
 
This patch removes duplicated code in frame calculation &  adds
megasas_get_frame_count() that also takes into account the number of frames
that can be contained in the Main frame.
FW uses the frame count to pull sufficient number of frames from host memory.
