Add the concept of a "user pointer" (similar to the void __user * in 2006-05-19T15:06:51+00:00 Michael Brown 2006-05-19T15:06:51+00:00 urn:sha1:d48d0fb1bb53262bf44a03dbe8388529f1566a1c the kernel), which encapsulates the information needed to refer to an external buffer. Under normal operation, this can just be a void * equivalent, but under -DKEEP_IT_REAL it would be a segoff_t equivalent. Use this concept to avoid the need for bounce buffers in int13.c, which reduces memory usage and opens up the possibility of using multi-sector reads. Extend the block-device API and the SCSI block device implementation to support multi-sector reads. Update iscsi.c to use user buffers. Move the obsolete portions of realmode.h to old_realmode.h. MS-DOS now boots an order of magnitude faster over iSCSI (~10 seconds from power-up to C:> prompt in bochs). iSCSI writes seem to be working (at least, the ethereal trace shows no 2006-05-19T00:20:08+00:00 Michael Brown 2006-05-19T00:20:08+00:00 urn:sha1:a280587cdeecb1ae96f56cd14d6e61b060aeee9e errors; still need to verify data integrity). SCSI response PDUs are handled: status and sense data (if available) are returned via the scsi_command structure. Updated iSCSI session parameter usage.

Headers that reflect a Linux header (e.g. if_ether.h) should also be in include/gpxe/, with the same name as the Linux header and, preferably, the same names used for the definitions.
