**************************** NOTE *******************************
|
||||
* How do we calculate MAX FCoE SCSI SGEs? Here is the math:
|
||||
* Max Egress WR size = 512 bytes
|
||||
* One SCSI egress WR has the following fixed no of bytes:
|
||||
* 48 (sizeof(struct fw_scsi_write[read]_wr)) - FW WR
|
||||
* + 32 (sizeof(struct fc_fcp_cmnd)) - Immediate FCP_CMD
|
||||
* ------
|
||||
* 80
|
||||
* ------
|
||||
* That leaves us with 512 - 96 = 432 bytes for data SGE. Using
|
||||
* struct ulptx_sgl header for the SGE consumes:
|
||||
* - 4 bytes for cmnd_sge.
|
||||
* - 12 bytes for the first SGL.
|
||||
* That leaves us with 416 bytes for the remaining SGE pairs. Which is
|
||||
* is 416 / 24 (size(struct ulptx_sge_pair)) = 17 SGE pairs,
|
||||
* or 34 SGEs. Adding the first SGE fetches us 35 SGEs.
