>Description:
I m trying to understand the driver code for IEEE 1394. I cant figure out the meaning of some constants defined in fwohcivar.h

#define	OHCI_BUF_ARRQ_CNT	16
#define	OHCI_BUF_ARRS_CNT	8
#define	OHCI_BUF_ATRQ_CNT	(8*8)
#define	OHCI_BUF_ATRS_CNT	(8*8)
#define	OHCI_BUF_IR_CNT		8
#define	OHCI_BUF_CNT							\
	(OHCI_BUF_ARRQ_CNT + OHCI_BUF_ARRS_CNT + OHCI_BUF_ATRQ_CNT +	\
	    OHCI_BUF_ATRS_CNT + OHCI_BUF_IR_CNT + 1 + 1)


I want to know what r these constant meant for and what is there use?Are these constants defined by the 1394 sepcification or is it OHCI chip dependent.
>How-To-Repeat:
1.     open fwohcivar.h
2.     goto line number 49
